I’m not sure I understand, either. My seats are directly across the stadium from the MUSS. The third down jump is still very much a thing, and they are as loud as ever. Makes me excited to see how much louder RES will be if we finally enclose the South end zone with seats and all that noise stays in the stadium.
The only thing I could think of is that they are sometimes a little bit late to show up, but by 5 or so minutes into the first quarter, it’s typically full. Then again, most other people in the stadium can’t be bothered to show up for kickoff either (or they leave early).
