Sure, Jamar Fletcher still has to prove he can be effective as the nickel back and the team has to decide on a dime back, but there are few questions about the starters.
In fact, this is one of the top starting secondaries in the NFL. Yes, Arturo Freeman will be in his first full season as a starter, but anyone who has watched this guy over the past two years will tell you he will make Dolphins fans forget about the departed Brian Walker.
Freeman will start at strong safety, and his athleticism and coverage skills have him earmarked for success.
At free safety, Brock Marion went to the Pro Bowl two years ago and easily could have gone last year, so the Dolphins obviously are in good shape there.
It's pretty obvious by now, also, that the Dolphins have two top-notch cornerbacks in Sam Madison and Patrick Surtain.
To give you an idea of just how strong the Dolphins are at this spot, consider that Madison has become a fixture at the Pro Bowl and there are many observers who will tell you Surtain is just as good, if not better.
We mentioned Fletcher earlier, and the Dolphins need him to come through after a disappointing rookie showing. But remember that this guy was the best cornerback in college in 2000. Fletcher learned some valuable lessons last season, and the Dolphins are confident he will make a big jump this season.
As for the sixth defensive back in the dime defense, the Dolphins figure to choose between Trent Gamble and Shawn Wooden, with perhaps Ray Green as another possibility.
The Dolphins figure to keep nine or 10 defensive backs, and might have some tough choices to make because a lot of their DBs also excel on special teams. In addition to Gamble and Wooden, that description would apply to Scott McGarrahan.
Also keep an eye on rookie Omare Lowe, whom Dave Wannstedt has consistently praised in the early days of training camp.
That's 10 defensive backs we've mentioned, and don't be surprised if all of them make the final roster.
The other DBs in camp — Delvin Brown, Cedric Donaldson and Zebbie Lethridge — look like long shots to make the final roster.
