So an ill-timed timeout warrants taking a swing at someone? Yeah...
BTW, if you listened to Gard's explanation of the time out (Michigan was playing pressure, rather than just letting them just run out the clock...think PJ Fleck @ MN 2020) it makes sense and he was trying to explain that to Howard. Howard, on the other hand...just lost it. Once you start the finger point into the face or chest...you're an asshole.
I'm no Gard fan, I think Wiscy often plays on the edge of dirty (can't think of a player I despise more than Davison). But in this case...Jawan is in the wrong.
