Yeah, just odd they weren’t off their feet. We’d do walk thru in the hotel (in a large meeeting room). I don’t think that’s common. Even as the home team, I don’t think UM does anything on a field all day Saturday before a night game like that.
For a night game. not completely unusual to do a mid/late morning walk through. You're right though, it's usually substitution groups, or stretching, things like that because you do want them off their feet. Also you will see some outside time when you have a long flight the day before, or there is a big climate change. (Cold to Hot/Humid, or vice versa). Most of this is hotel ballroom stuff, but again, not completely crazy to have an on the field walk through in the a.m. before a night game. I suspect they may have also had a new wrinkle or two they didn't want to show. (Someone gets the idea to put in a trick play on special teams, for example, and that's something you might do on the Friday walk through and again the morning of a game). Again, just guessing but all of that is plausible.
Bottom line: Brian Kelly is a total C*ck and I hope he gets gonorrhea
