If Hawk is out for the year, like speculated.. I think it is time to move Barnett outside and insert Bishop into the middle.
A couple of notes on why..
1) Utilize Barnett's speed more effectively outside.
2) Nick won't have to fight through blocks in which he seems often to get washed out or down field a couple of yards.
3) Bishop would help stiffen that interior rush defense and Barnett would be able to help close the sidelines with his speed.
4) Bishop is too talented to keep off the field over Chillar or Poppinga.
But most of all.. I hope Hawk's injury isn't as severe as first thought.. dude has played well.
