He's a really, really horrible human being?
Seriously, he's about as slimy a head coach, as they come. I'm guessing you know his history, but if you don't, he got his first HC job at Rice. They had a good year (went from 1-10 to 7-5) and he said all the usual, "I want to take Rice to the big time...I want to be the Joe Paterno of Rice...etc." He signed a big, new contract extension and bolted for Tulsa about 2 days later. He stayed there a couple of years then left for Pitt. He stayed there all of 1 year and left for ASU, employing the always classy, having his Football Ops guy text the team to tell them that the coach is gonzo.
I think I've posted it before, but the Marching Owl Band (MOB) did a great halftime show when Rice played Tulsa, the year after he left Rice. http://mob.rice.edu/history/scripts/200711240
There is nothing wrong with coaches leaving their current jobs for a better one, and they get to be the judge of what constitutes a better job. But there are good ways to make that transition and there are bad ways to make that transition.
Is he really a horrible human being? I don't know. But his actions as a head football coach suggest he might be.
Was it two years ago that an ASU player clotheslined a CU player during a return. It was bad. Like, the player should have been ejected and maybe sat out a game or two bad. After the hit, the cameras focues on the guilty ASU player, and he and a buddy were pointing at the jumbotron replay laughing and dancing, while our player was down on the field.
I'm pretty sure that was Graham's first season. Culture starts at the top. Graham reminds me of Erickson.
