As the director of the Grizzly Marching Band I should probably weigh in here. I can assure you we were there the whole time - from Griz Walk through the end of the game. We love supporting the team and were doing our best.
What you may have seen is when we left the stands to stage for halftime. We usually leave the stands with about 6-7 min. left in the second quarter.
I base that on whether we're seeing a lot of running plays or more passing plays. The time disappears faster with running plays and we need to be in position, and clear of the tunnel before the half ends.
I think the team enjoys our support but they really don't want to encounter 150 of us coming down the tunnel when they are heading to the locker room.
As for DJ Briggs, his contribution to the game isn't impacting what we do between plays to provide music. He has more flexibility in the way he can mix music than just playing a stock track from the booth. It gives some variety in those times where the PA music is used. It hasn't caused the GMB any problem.
