You are correct on all counts. I'm a big fan and have been since high school. I always predicted big things from him. He is a very unique individual and is easy to dislike if you're not a PSU fan. But I would compare him more to Cassius Clay than Thomas Gilman. Not many loved Clay and even fewer young Ali, but fans worshiped Ali later because he dazzled fans, matured, and became less angry.
All that said, I would rather he not be so brash and disrespectful to his competitors. I think his mouth writes some checks his body can't cash right now. I know that he has plans for his brand and business career (which will revolve around that brand). If I were advising him, I would suggest he work to increase his likeability quotient. It will probably come naturally with age as it did with Ali and Gilman.
