Purdue-Michigan isn't considered a major rivalry, but there's some bad blood brewing between head coaches Rich Rodriguez and Danny Hope.

After today's Purdue victory at Michigan Stadium, Hope reportedly introduced Rodriguez to Boilers offensive lineman Zach Reckman and said, "Thanks Coach, we appreciate what you did." The Big Ten suspended Reckman for a game in September after he delivered a late hit to a Northern Illinois player after Purdue lost to the Huskies.

"I was a little disappointed that after the game their coach seemed to bring the lineman over like I was the reason that his lineman got suspended for that one game," Rodriguez told reporters in Ann Arbor. "I don’t know where that came from. I talked to him on the phone and told him that wasn’t me that -- this is way back when. I didn’t have anything to do with that young man getting suspended for that one game."

Rodriguez had previously he would be alert the Big Ten of any conduct issues after the league suspended Michigan linebacker Jonas Mouton for punching Notre Dame's Eric Olsen. The Michigan coach made a reference to seeing a conduct issue on Sept. 19, presumably Reckman's late hit.

"As a coach you say, 'OK, the precedent will be set,' and that's why I saw we’ll look at every act," Rodriguez said in late September. "And, in fact, it's funny you say that, I saw a Big Ten game, in the locker room as we were leaving, highlights, and it was the end of the game and a guy jumped on someone on the last play of the game and did a little of this right here. Now is that a non-football act? It probably is, so that may be turned in and see what happens."

I'm not sure where this is going to go. Unlike the SEC, the Big Ten rarely has coaches publicly sniping at one another.
