Well considering your height I would either say defensive end or outside linebacker depending on how fast you are.
Defensive tackle
RunningBack
Cheerleader.
Bench Warmer
I think you should be a running back because you're so fast.
fullback?
If your fast: cornerback or wide receiver
cornerback or safety
Anyone you choose! - Most coaches would have you on the line
In 7th grade you would probably be an offensive or defensive lineman.
Punter or placekicker. No speed required.
No we football should not be a class of college because we come college for studing and to learn something
