Looking like a defensive end to me.. Big guy, strong I'm assuming. Defensive ends are the guys constantly (95% of the time) trying to get to the quarterback and sack him.. Or trying to stop the run. You could also be a fullback (I was a fullback.. Never got credit for it though). Your school may or may not run a fullback, but the fullback is the guy the blocks for the running back, creating holes for him to squeeze though.
Wide recover or tuning back if you have some muscle
Defensive of end Full back Or offensive of gaurd
You kinda heavy set, but short. You could be a runningback, like a strong one ( Eddie lacy etc.) you can try to break the barrier of a small QB, ( russell Wilson etc) be a DT, it's really up to the coach tho.
Running back or wide reciever
