I thought there were no position switches? Or do you guys just mean via the depth chart?
I would love to move an OLB to a DE or start a franchise with a 3-4 team and convert them to 4-3, but unfortunately the game won't let you and running a 4-3 team with 3-4 personnel gets a little tough with roster space.
I believe block shedding is just for shedding run blocks, and not the passing game.
What I did was edit, Ryan Kerrigan before I started my CCM. So you have to have a player in mind you want to do it with before you start it.
