Apparently, the Jim Harbaugh-to-Michigan rumors have someone skittish.

The San Francisco 49ers coach and former Michigan quarterback opened as the betting favorite to be Brady Hoke's successor as the next U-M coach.

Harbaugh hasn't addressed it when asked in his news conferences.

But someone may know something, according to a tweet today from R.J. Bell, the founder of Pregame.com, a sports betting website.

Bell later tweeted that the website reports that money continued to come in on Harbaugh "no matter how low they made the odds."

He later wrote that the website was afraid "someone might know more about his coaching situation than us," which prompted the odds being suspended.

Harbaugh has reportedly been at odds with 49ers management and, even though he has one year remaining on his contract, he's expected to have other NFL suitors as well.
