Carpenter looks solid, strong at the point of attack. Thought he was OK in pass rush, doesn't have the blazing speed of Lawson. I think he would make a good S OLB. How much more upside does he have?
Wimbley, looked rock solid as well, bigger and quicker verson of Carpenter, but he has never played OLB before, so that would be a big learning curve. He looked like he has enough bulk on him to where he could make the switch to LB, but coverage wise he might be a liability.
Lawson has SPEED and that cannot be taught, but you have question his size, he looks really lean and don't know if he can bulk up and handle the Strong side. But his speed is crazy, he might have the most upside out of all of them.
