Whilst I'm a Dennard fan, let's not go putting him in Canton just yet.
The big issue is the second Safety spot. I'm much happier with Wilson than ANYONE else right now, and that's saying something. If the ball is in the air, I have absolutely no faith in Chung and co. getting near it. Either we need to scheme better, or we need to try another body there.
I think McCourty's fine at LCB (that big gainer late on was typical of the type of opponent we were playing and I think that play gets made against the other 30 teams in the league), but that RCB spot is a big concern too.
Arrington should be nowhere near the team, simply, and Moore is neither here or there. I'd play Dowling, and let Dennard see time with Moore in the slot. Not sure what happens at Safety though.
