Jim Harbaugh sent shockwaves through the college football world when he became a Troll God and invited every college coach in America, including those that had been whining about his satellite camp tour, to participate Michigan's main summer camp in Ann Arbor from June 14th to the 17th.

One head coach has already accepted: Montana's Bob Stitt, who's considered by his colleagues to be an offensive innovator.

It'll be interesting to see which coaches accept and which deny Harbaugh's offer, and we'll keep track of it all here.
