Possibly.
- Playing on a team with a better O-line - Better protection = better stats. (Plus an injury would likely lower his draft spot)
- Playing on a team that is more likely to be playing for a NC
- Playing for a blue blood with the media connections to better push for a Heisman
All those things can get you a higher draft spot. I hope his love for State is enough to outweigh all this though.
With that said... My dad went to State. My BS is from State. Both my kids graduated from State, but If he were my kid, I'm not sure what advice I'd give him. I guess I'd have to see what all the options were.
