My expectation is that there will be a ton of NFL executives in Ann Arbor today for Michigan's Pro Day to watch JJ and all the draft eligible Wolverines participate in drills. Jim will be attending with Jessie Minter and Ben Herbert. 7 NFL Head Coaches and 9 GM's are expected to attend as well. Plus a ton other NFL OC's, DC's, and other position coaches.
JJ is probably the most discussed QB on ESPN right now as NFL team decide if he is a top 5 pick or a lock for Minnesota at 11. I'm truly biased but I watched a lot of Caleb Williams and didn't watch Heisman winner Jayden Daniels at all, I think JJ makes the best decisions out of any of them.
