Opinions on College Football Walk Ons?

I'm not getting a football scholarship, but I have good grades, I'm looking to be a walk-on tight end for the San Diego State Aztecs.. I am a hard hitter, Blocking AND receiving Tight End. 2 years varsity experience 5'10 205 pounds, STATS: Bench-285,Squat-420,Powerclean-225. 7% body fat. Could I make it?, Obviously, I have to be attending the school to try out, but I want to Figure out witch school I would want to go to for sure, and actually have a chance at playing at that particular school. Anyone with past experience will probably be the most help here, thanks guys.
