It'll be interesting to see what direction Tennessee goes. They were headed in a good direction with Jones after the Dooley debacle, but he stalled out and then plummeted. It's a good job with the amount of resources available, but not a great job since you do have to venture into other states (Georgia, Florida, South Carolina, etc.) to get the better recruits.
Obviously the Gruden rumors will get a bunch of attention, but it'll be interesting to see if they try to go high-profile (Les Miles, Chip Kelly) or for a younger, up-and-coming guy (Matt Campbell, Mike Norvell, PJ Fleck). Or they could split the middle and go with a guy like Dan Mullen or Jeff Brohm.
