The main problem from every angle is "consistancy".
For the bands...SU is probably the best at paying attention to the game. A couple times SU has slipped...but, for the most part, everything played is in context with the game (Fanfare #2 for sacks...fight song snippets...etc). If it did happen at the SU/JSt. game...SU playing was more of an exception...cuz, that's usually not the case (unless, the game is already out of reach).
More bands need to be more consistant. I can only speak as a Houstonian and say that PV and TxSU has been HORRIBLE with it in the past. Don't know if they've straighten it up...but, both used to straight up come to the games to pay attention to everything BUT what's going on on the field. And, that attitude is totally wrong for a band to take.
Refs have to be more consistant in calling it. From week to week AS WELL AS from quarter to quarter or play to play. Can't let a band get away with it for 3 Quarters...then, wanna clamp down in 4th. Of course, the bands will look at you crazy and push the envolope the rest of the game.
And, if it's an HBCU game...I understand promotions and sponcerships...but, if you know the bands are important to the HBCU atmosphere...you can't have the PA blasting commercials during timeouts. Commercials are most effective visually, anyway...so, there's no reason to blast every commercial.
I do agree with some of the other posters, though. Im a bandhead as much as I am a sportsfan and visa versa...and, even I don't wanna hear the bands blasting during the ball being in motion. As a whole, we do a horrible job at watching the actual game on the field
