I would hope Brevin's "handlers" advise him to stay unless he comes back this year, stays injury free AND averages north of 150 yards/2 TDs a game. Its not a bad thing to play a 4th year of college football and develop.
Brevi, if he doesn't play in anymore games, will BE LUCKY if he goes in the 4th or 5th round.
I hope he gets healthy and balls out for Miami, then goes and gets drafted. Hopefully he sticks around to next season.
