It's awful. The in-stadium video boards show few enough replays, and virtually no replays of disputed/disputable plays. There's almost no use of any slow motion replay.
All of these effects, once limited by Conference rules, have now been allowed. But Michigan Stadium video operators, always behind our rivals in East Lansing and Madison (having seen both for myself) and to some extent in Ohio Stadium, seem to have done nothing to utilize the new freedom granted by the Conference.
Time for Michigan Stadium to get with the 21st century for video replay.
