I finally saw a good view of that whole pre-game walk thing. I will try to embed it here. A few things of note.
1. Any of us who have played college sports will tell you that schedules for warm-ups and game are printed and posted. Sparty knew what it was doing when it came out late.
2. Dantini is actually IN FRONT of the walk at the start. Remember what he's seeing, about 5 Michigan guys doing their warm-ups right where he wants to go full prison league football.
3. They are wearing helmets. Now, maybe they do that every time (mgoblog sleuths, please investigate), but my gut tells me the helmets are in anticipation of a fight, a fight they wanted to start before the game.
Anyway, here's the link (I think). What do you all say?
