Colvin's nursing an ankle injury, which those of us without sight impairment can tell, has had a clearly noticeable effect on his level of play. Before the injury he was a beast against the Chargers, and made some good plays against Buffalo. He sat out most of the Bengals game with the injury and has been trying to get back to 100%. For those saying he hasn't done anything special since the dislocation, I think you're way off. Colvin had 8.5 sacks and 1 FF in 2006, and 7 sacks along with 2 FF's in 2005. For those who don't realize this, the Patriots don't play a sack happy defensive scheme. Really, to me Colvin's 8.5 sacks in the Patriots scheme translates to 11-12 sacks in a scheme like the Bears, Steelers or Chargers. He is also used in pass coverage a lot more than some might realize.
AD: While I've always said I believe him to be a better OLB than ILB, I do think he's been doing a nice job on the inside. Let's not forget that he's also been fighting through injury, and if you're watching him, the injury has taken a noticeable effect on his speed & pass coverage.
Why do I keep seeing "all our LB's are slow, and have trouble in pass coverage"? AD's not at all slow when healthy, and he's good in pass coverage. He just needs to get healthy.
Now, if we're simply saying that we'd like to have another LB with speed and pass coverage ability, then I'm in agreement, but don't sell AD short.
I'd like to draft Rey Maualuga, and believe me, he's faster than his listed 40 time. The guy has sideline-to-sideline ability, stacks hard, delivers punishing blows/tackles to ball carriers, good quickness, and is a smooth mover for his size. He's the type of high intensity guy that I want back there. His size is great for the position (6'3" 255lbs) as well. I believe Maualuga would be even better in the Patriots system than what he has shown to date at USC.
Karlos Dansby is definitely an option this offseason. He's one of the few LB's who'll be out there that I believe could come into NE's defense and be effective his first year. His age (only 25) is also a plus (for me anyways).
