late 70's early 80's college sports movie

[mx949]

Looking for a movie that was late 70's maybe early 80's about a college football player.  it was on a old cable system called spectrum 2.

I remember a scene where this guy was a hot shot in high-school and shows up to college thinking he will be the big man on campus.  there is a part where he has to throw a ball through a tire but cannot seem to get it.
