The future at running back may be a little hazy, but there are few teams in this league that can boast about having two backs as talented as Ronnie Brown and Ricky Williams. Sure, Ronnie has had his injuries, and Ricky has had his drugs, but when both are on the field together, they have been brilliant.

The studly one-two punch has been given the nickname R&R Express, and in order for the Dolphins to do what they want to on offense in 2010, that train is going to have to keep on rolling all season long. The addition of Brandon Marshall gives Dan Henning the resources to open up the offense a bit, but in reality, having a legitimate threat at receiver for defenses to scheme around, opens up more space than ever for Ronnie and Ricky.

Teams can longer stack the box to stop the run. Dare I say this will be their most successful season, together? First things first though, Ronnie is going to have to stay healthy. Something he has only accomplished once in his career, which just happened to be the magical turnaround of 08'. Secondly, Ricky can't start showing any signs of slowing down. Even though he's now 33, that isn't so far fetched, considering he spent nearly three whole seasons out of football, and he has spilt carries with Ronnie for the majority of the second half of his career. Still though, he could hit the wall any season now.

This time next year, the running back position may be completely up in the air. But for now, at least, Dolfans can relish in the fact that Miami has two of the most talented in the business.

Safe

Ronnie Brown: This could be Ronnie's last season in Miami, but there's no question he's got top ten talent at the position. He makes the wildcat what it is, and has an excellent combination of power and athleticism. The durability issue has almost single-handily cut his career down, however. Has it just been a misfortunate case of bad luck, or is he really this injury prone? Whatever the case, hopefully he's due for a full-sixteen game season, because the running game and the offense as a whole, takes a huge hit when he can't go. Let's not forget he still has been rehabbing the foot that suffered the Lisfranc fracture, but all signs point to him being 100% by the end of the month.

Ricky Williams: How much longer can he keep this up? Many backs stumble to mediocre status once they hit the dreaded age of thirty, but Ricky is still running strong at thirty-three. He probably can't carry the load by himself anymore, which was evident by the way he wore down in the last few games of the season, but if Ronnie can stay healthy, and the Dolphins can manage to keep both players' workload relatively even, he still has the potential to be arguably the best complimentary back in the league.

Patrick Cobbs:The return of Patrick Cobbs may be more significant than you think. He's the ultimate utility player. He returns kicks, lines up at receiver, executes reverse plays out of the wildcat, and steps in at his actual position when called upon. Many argue that he's Sparano's favorite player, which is consistent with the way he gushes about Cobbs in press conferences. It's still uncertain if he will be able to return to his old-self a year removed from an ACL tear, but at the end of the day, he does too much for this football team to not find a spot.

There are many unkowns surrounding the Dolphins' defense that are sure to make or break Mike Nolan's efforts at turning around a unit that finished 22nd in the league, in the same way he did in Denver a year ago. Among them are Randy Starks' transition to nose tackle, how the outside linebackers shape up, and if Chris Clemons can develop into a quality starting free safety.

How good the secondary can be, likely falls on the shoulders of Clemons. Vontae Davis and Sean Smith are expected to make significant strides in year two, and the strong safety spot is already established with veteran Yeremiah Bell.

If Clemons can live up to the expectations that have come with the coaching staff and front office talking him up all offseason, then the pass defense, which was arguably the Achilles heel of the entire team in 09', will be in substantially better shape then it was last season.

Safe

Yeremiah Bell: One of the league's most reliable tacklers is obviously safe on the roster and safe as the starter at strong safety. He's fresh off his first ever Pro Bowl appearance, and should be able to maintain that high level of play for at least one or two more years.

For future sake, hopefully Reshad Jones gives the coaching staff a reason to believe he can be Bell's eventual successor at the position, if free safety doesn't work out for him, that is.

Chris Clemons: When Parcells and Ireland failed to woo in the services of Antrel Rolle and Ryan Clark in free agency, and chose not to invest a high-round draft choice in a free safety, Chris Clemons instantly became a lock to make the roster. Perhaps even more surprising, has been the team's constant praise of Clemons' offseason work.

Everyone knew he had the physical tools to become a quality safety in this league, but mental mishaps reportedly prevented him from earning the starting job, even though Gibril Wilson was in the midst of a nightmare campaign. Parcells gave the fans a reason to believe those mental mishaps are a thing of the past though, when he confirmed that Clemons had one of the better ratios of snaps to mental errors on the team during offseason workouts.

That trend needs to contine when the pads come on and things speed up a bit, and more and more information is thrown at him. If his mental progress starts to digress, expect Reshad Jones to enter the picture, and a heated competition to unfold.

Tyrone Culver: To many people's surprise, Culver hasn't been given the opportunity to compete for the starting free safety job. Instead, he has been getting the backup strong safety reps. Still though, he's likely a lock to make the final 53-man roster because the coaching staff knows what they are getting with him. Which is a consistent, solid back-up, with value on passing situations.

With much of the sports world glued to their TV sets this morning, looking for any insight into what the NBA's crazy free agent class is going to do, here at Phins Phocus the start of July simply means that training camp is right around the corner. So without further ado, let's get the first installment of this year's training camp preview underway.

What better position to start with than quarterback? How good the offense can be is invested heavily into if Chad Henne can take that next step as a quarterback. And with four quarterbacks on the roster, this year's camp is sure to produce a heated battle for that final roster spot.

Locks

Chad Henne: Although, this is without a doubt Henne's team now, this year's camp will be crucial, as all eyes will be looking to see if he is ready to become a franchise quarterback. All indications suggest that Brandon Marshall will be ready to roll at the start of camp, so developing a chemistry and a rhythm with his new go-to target will be a must. Sparano recently praised Henne's efficiency during OTA's and minicamps this spring, but looking back to last year, he had a bit of a rough camp, especially in the two-minute drill. That better not be the case this August.

Chad Pennington: The front office thought what Pennington brings to the table as an insurance policy and a mentor, was enough to bring him back to Miami. Many envision him as player/coach, who eventually takes over as quarterback's coach when his playing days are over. Those days may be over sooner than Pennington is willing to admit, with yet another shoulder surgery that likely weakened an already "noodle" arm. Still though, Pennington wants to play beyond 2010, but doesn't want to rush back, and is comfortable playing behind Tyler Thigpen as the Dolphins' third quarterback. There have been rumors he is headed for the PUP list to start the season though, which could open things up for the Dolphins keeping four quarterbacks on the initial 53-man roster.

A player that saw his tackling production cut in half last season, has as many game changing plays in his five-year career as many do in one season, has made a fool of himself in the past with his mouth, and is coming off a season ending Lisfranc injury, shouldn't be a lock to start, right? Well the perception among many is that Channing Crowder, despite coming off the worst statistical season of his career, is still penciled in as the starter next to newcomer Karlos Dansby.

Crowder has been solid in the past, don't get me wrong, and if he can return to the high-level of play that saw him rack up 103 tackles in 06' and 113 in 08', he should be the starter, no doubt. And we shouldn't underestimate his value against the run either. In the four games Crowder missed the last two seasons, the run defense simply fell apart.

In those four contest, the Dolphins run-D yielded 154.4 rushing yards a game, and a staggering 5.1 yards per carry. Now, that may speak volumes about how horrible the linebackers were behind him, but it's been clear, nonetheless, that Crowder makes the run-D better. Still though, do his struggles in the other elements of the position make him vulnerable to former Charger Tim Dobbins?

Because just what we saw with the naked eye, doesn't justify how bad Crowder was in coverage and blitzing a year ago. I think Pro Football Focus really puts things into perspective, by ranking Crowder's miserable 09' campaign 49th out of the 54 inside linebacker's listed. As expected, Crowder received a positive 2.4 rating against the run, but his -5.6 coverage rating, and his -1.6 pass rush rating, really sum up how one-dimensional he is.

Enter Tim Dobbins, who has brought over in that draft day trade with San Diego, that more notably saw the Dolphins swap their 12th overall selection for the Chargers' 28th and 40th overall picks. He has been described as a "core special teams" player by Jeff Ireland, but when you factor in how Ireland's comments really mean nothing, how Dobbins put up three more tackles than Crowder in 418 less snaps, and the fact that Dobbins has obviously impressed this offseason, which can be seen in his recently signed extension, it's easy to see why he could push Crowder for the starting job.

So let's take a look at the film, to see what exactly the Dolphins are getting with Dobbins. Click read more to see the video and some analysis.

With really nothing going on this time of year, outside of rookie negotiations and signings, you could literally here a pin drop, due to the dullness and silence that is late June. Consider Brandon Marshall's comments over the weekend at his youth football camp the pin.

“I’m not making a prediction,” Marshall told the Palm Beach Post. “But this is going to be a great year for us, and for me probably the best year I’ve had.” Nothing earth-shattering or controversial, thankfully, but something to talk about nonetheless.

While Marshall's lofty expectations for the Dolphins and himself might get fans all wound up with excitement, realist may make the case that career numbers are unlikely with Miami's dedication to the run.

So let's get to Marshall's statistics thus far, and how often the Broncos have ran and passed compared to the Dolphins, to get a feel for what Marshall is capable of.

Brandon Marshall

As you can see, it's going to take at least 1,326 yards receiving and 11 touchdowns for Marshall to have career numbers. Of course, if he has a little less than 1,300 yards but surpasses his 09' touchdown total, or has one or two less touchdowns but puts up more yards than ever, you could still make a case for 2010 being his best season.

Whatever the case, it's going to take a very prolific year for Marshall to statistically one-up what he has done in Denver. But will he get as many opportunities in Dan Henning's offense? Let's take a look.

Miami Dolphins

Denver Broncos

Those totals come out to the Dolphins passing the ball about 52% of the time, while the Broncos aired it out around 54% of the time during Marshall's four year stint in Denver. Those percentages don't seem to indicate that Marshall's numbers are going to decline too heavily in Miami's run-first attack.

Obviously, these statistics don't take into effect things like having to throw the ball because you are behind, or milking the clock with the lead, but they seem fairly parallel with each team's philosophy. And when you take into account the fact that Marshall gives the Dolphins the ability to open things up a bit, meaning throwing the ball more, Marshall having a career year in 2010 doesn't seem too far-fetched after all.

And maybe he wasn't even talking about individual accolades when he made those comments. Maybe he was suggesting that by winning ball games, and making a serious playoff run, the team's success would define 2010 as his best season yet. But then again, career numbers from Marshall would go a long way in making those team goals possible.
