I've been to games in about half of the conference in recent years. One thing that occurs to me -- and it may be subjective -- is that Michigan Stadium has traditionally done fewer scoreboard replays on close/disputed calls than any other.
I was reminded of this just now watching the game in Camp Randall, and it is the Badgers that always really struck me as doing the most replay work by far. MSU is next, and OSU after that. It may be that those are the stadia that I've been in most. Michigan seems to be about the least.
Absent any metrics, does anybody else agree? Has anybody been to more than half the B1G since all of the current jumbotrons have been in place?
Maybe this situation will be corrected with the new scoreboards.
I haven't been in many of the BIGs but based on what I have seen in Michigan stadium you are probably right - my impression is they have not been heavy on replays. They show them but on the low frequency side, especially with the more controversial calls.
Not sure where this stands now but at least at one point the NFL was discouraging replays on the more controversial calls, to keep the rioting to a minimum. Colleges I presume are left more to their own judgement.
