Let me add a couple to your list.
6. Our games are much slower now under Holtz than under Dykes. Lots more dead time now in between plays. Fast-paced football is much more fan friendly. We've had much less frequent Move The Chains chants with Holtz.
7. The video board isn't as engaging as it used to be. Those videos with Terry, Kix, Trace, All I Do Is Win, All the Way Turnt Up, etc. were much more engaging than the videos we're using now. I like the Flex Cam better than the Kiss Cam, but other than that, I think the older videos were much more engaging.
And yes, I agree it's time to move on from Wagon Wheel. This isn't North Carolina or Tennessee. Let's find another song for the fans to sing along to.
