Is 5 foot 9 and 170 pounds a good size to play running back on your senior year of high school?

its a great start...all you have to do is gain great chunks of yards on the pitch and outside hand offs and do not fumble on the inside ones. it wouldn't be good enough fr college yet but you will gain eight when you get there. I am 5 9 170 and i am a running back at college. If you have good speed and acceleration, you can be a dynamic back. i do not block well. but i can catch the football and its helps our coaches t ave good options on the passing play.

What you need is to have speed of at most 4.4 and general quickness. I run a 4.16 and can catch on the run which helps me stay as the third down running back and kick returner
