Hat tip to the Commodores; they played a great game. However, I hope that Heupel and Danny White recognize that losing to Vanderbilt in Neyland stadium, especially coupled with the squandered opportunities against UGA, OU, and Bama, is completely unacceptable. There has to be accountability for this loss and this team's inability to make the right plays in the big moments this season.
That being said, what the program needs are tweaks, not wholesale changes. An assistant or two, perhaps a coordinator, need to be replaced. I don't think elaboration is necessary there. This thing is a work in progress, and we have to remember both where we came from recently (the post-Fulmer dark age) and where we come from historically (a top program in college football). Let's not throw the baby out with the bathwater...but definitely get rid of that bathwater though it's friggin nasty.
TL;DR version: Someone needs to be fired, but if you think that someone is Heupel you need to put down the bottle and step back from the ledge.
