6'5 high school offensive back possible?

Or impossible? Max bench is 310. Max squat was 555. But i am going to boot camp and they have a lot of running and no weights so my squat will probably go down. Got a plan to keep my arm strength up though. Going to boot camp so my endurance will be high by the end of that. I got okay speed. Above average but not dusting people. I can catch. I have never run the ball in a game but during practice i am pretty good at it. Never been brought down on the first hit. I would love to play running back but i would play fullback too. But is that even possible in high school ball? I mean even most nfl backs are short right? I don't really like playing offense to be honest i just wanna score some touch downs this year and i think i would put in more work then the starting back. Hes scared. Oh and if it matters he is like 5'7 150 real skinny. He says he is fast but according to the people on my team hes average.
