What did he quit? On a team? Two teams? Three if you count UNLV? Players are transferring all over the place, are they quitters as well? Even those that come here from somewhere else? Phillips, he all but quit football, but came back.
Seems he just realized he wasn't good enough. It happens a lot, but for whatever reason he didn't quit long ago. He kept trying, how hard, no clue, but it wouldn't have worked even if he was the hardest worker.
I'm not really disagreeing with you, but what did he quit? You could say it another way, he kept trying. Glass half empty or full?
