Bodden was a top ten corner last season. If Butler can avoid a sophomore slump and keep improving at the rate he did last season, that's two very good starters for 2010. However, behind them for nickel/dime packages, the ancient Springs was a degree or two better than Wilhite and the dropoff from Bodden/Butler was farily substantial. Then there's Wheatley who appears to be close to a bust. Arrington is very enthusiastic, but may not ever be more than a great ST guy.
I like Wilson a lot. I think he could step in and be slightly better than Butler from the get-go. If all the 1st-round-worthy pass rushers are gone by #22 and Wilson is still on the board, I'd be very happy if BB took him. I like McCourty as well, but think he's no better than Butler and wouldn't become a significant contributor till late in 2010 or into 2011. Not so sure about Kareem Jackson and I feel that there's a significant dropoff in CB prospect potential after him. Either way, I do feel that we need one more truly solid CB.
However, I can't take the CB position out of context. It is also true that getting a pass-rush that can get home in under five seconds would do wonders for the performance of the entire secondary. It also seems to me that upgrading at safety would help a whole bunch. Meriweather is very good in coverage, but tackles like Sean Weatherspoon. McGowan is great in the box, but, for me, that doesn't compensate for his uncanny ability to screw up coverages. Sanders is a good, solid #3 guy in both respects, but Chung is still in the wait-and-see phase (but coming along much more slowly that I expected). Lockett is like Arrington. It should also be noted that Darren Sharper is still available, though that's a serious longshot.
The ideal, for me, would be to have two starters who can cover like Meriweather and tackle like McGowan with Sanders as the #3/reserve guy. The good news is that there may be a few underrated safety prospects available in the mid/late rounds this year. The other (possibly) good news is that, in January, the Pats added Corwin Brown, an experienced NFL secondary coach, to at least supplement the efforts of young Josh Boyer (2009 was Boyer's first year coaching DBs at the pro level). Perhaps this will speed the development of Chung, Butler and Wilhite and maybe even "fix" Wheatley (Kerry Rhodes actually played fairly well while being coached by Brown). Brown may also have some valuable input about this year's draft prospects vis-a-vis the guys already on the roster.
