Agree with the guys here. Guard has improved - and we've got depth. Nickel - which was a huge need appears to be filled with healthy competition between Gaines, Roberson, McGee and Greg Reid to back up Joyner. Backup QB has obviously improved with the addition of Hill - and I like what I've heard about Gilbert as well. Don't underestimate the impact Tre Mason could have on our RB committee. I think between him, Stacy and Pead we have a bit of a grinding attack there. DT has improved simply by adding Donald to the rotation.
RE: WR. I feel the position is improved - but not necessarily by the addition of players (eg Britt). Its a young group and every rep is more experience. They will get better with time. Perhaps their development hasn't been as quick as we'd hoped but who knows what Tavon Austin, Stedman Bailey, Brian Quick and Chris Givens ceilings are??
