Aaron Rodgers drives the ball down the field, but Matt Flynn has a very average arm. He runs that offense almost as well. At its roots, Green Bay still runs a West Coast offense based on timing. If Keenum gets the ball out on time, he's fine.I don't think Green Bay is a good offense for him personally. They ask for their QB's to drive the ball down the field and I think that would expose his lack of arm strength more than anything.
The combine didn't even expose what I believe to be Keenum's biggest weakness. I think he has real trouble with pressure up the middle and is too quick to bring the ball down rather than slide in the pocket. It probably has a lot to do with his size and inability to see over the rush. That's another reason why I think he should go to a team that moves the pocket around. Like the Packers do.
