Traore har improved greatly, i agree, but i cant see him as our long term LB. I dont think he has enough to offer going forward, and after all he is really more suited for CB.
Other much improved players are Finnan and Carragher. I used to think Carragher was a great fullback, but didnt have the understading and tactical nouse to play in the center, but he's proved me terribly wrong so far. Long may it continue,
