Why Does Rashard Mendenhall Hate Ron Zook?

Rashard Mendenhall just finished the most productive season in the history of Illinois running backs and was drafted in the first round by the Steelers. He is, of course, rapt with ecstasy when talking about the guy who put him in this position:

"To tell you the truth, as long as Ron Zook is there it will be hard for me to support the University of Illinois football team," Mendenhall said.

Uh. Dude. In a wide-ranging interview with an Illinois newspaper named the News-Gazette that declines to mention where the hell it's located, Mendenhall drops that bomb and many others. To wit:

His brother and teammate Walter is the only reason Mendenhall didn't transfer before his breakout 2007: ""There was a point where we were at the stadium and I was ready to start walking out and my brother stopped me."
His animosity had nothing to do with "what happened to" his brother, who is going to graduate and transfer to I-AA Illinois State for his final year of eligibility: "It's so much more than that. It's so much that's going on right now, that went on with me that people don't know. It's hard for me to support how things are done."
Ron Zook eats babies.*

Like I said: dude. I think we now know why the hyper-talented Mendenhall spent his first two seasons stuck behind decent but uninspiring backs. Well... sort of. At no point in the article does Mendenhall say why he wants Ron Zook to play in traffic, just that "everything wasn't as it appeared to be."

Well, why not? Does Zook have three heads? Does he shave his legs? Did he walk over to Mendenhall's apartment every morning and take a dump on the porch? INQUIRING MINDS WANT TO KNOW.

*(Silly blogger, Ron Zook doesn't eat babies. Babies are for Maxiell.)
