While Jim Harbaugh is busy pissing off most of the college football world and subsequently playing dumb about it, a couple of his coaching contemporaries are having some fun at his expense.

On Wednesday, former Wisconsin head man and current Arkansas coach Bret Bielema took to social media with a tongue-in-cheek thought about the Wolverines' upcoming open practice in Bradenton, Fla.

Not long after that, someone Bielema had some epic run-ins with during his Big Ten years joined in.

Dantonio and Bielema? College football politics makes strange bedfellows.

In theory, Bielema and Dantonio, and any other coaches and scouts, could attend Michigan's open practice at the IMG Academy on Friday. Will they? We'll just have to wait and see.

Could you imagine a lunch between Dantonio, Beilema and Harbaugh, though? That would make for some interesting conversation--or some tense, awkward silence.
