Honestly...I'm shocked we haven't went out and brought back Jonathan Cooper. He was starting to really play well @ the end of last season.
But a shuffle @ this point couldn't hurt...
My idea might sound too radical...but I'd run w/ this...
LT-Martin- He's our best O lineman....and he's played there before.
LG-Cooper...better than Conner
C-Looney...servicable
RG-Collins...people have keyed on him...exposing him.. using speed. might utilize his power better as a RG
RT-T. Smith...no longer elite on the left side..but by moving him to the right side...now you can give him help w/ a TE
