I'm ready to receive the backlash on this but...
I don't think Greg Johnson is a cornerback. He is too stiff in his hips and doesn't turn quick enough. He didn't impress me as anything special in his army all American tape. He strikes me as more of a RB with his build and the way his hips move. He has lateral quickness and a shake and bake to him on offense. On defense he just looks to lack the agility and flexibility. Blades has that, bookie has that, Lenoir has that. This guy has a bigger boned frame and looks more like an ox than a cheetah. If you put him on defense he needs to be at safety to come up to hit and also to run stop. Just my observations.
