I have seen this post more than once, so I decided to reply (and I accidentally liked it, lol):
spudvol: "If she wanted to live in Knoxville, why didn't she move here anytime in the last 4 years? She has no reason to stay in Tampa if Knoxville where she really wants to be."
It could be that their Tampa home sunk in value with the crash, and they didn't want to move and take a loss, when they didn't need to live anywhere in particular for Gruden to work for ESPN and MNF. It could also be that they anticipated Jon eventually returning to coaching, so they didn't want to move, only to move again in a few years. Or, maybe they just really love Tampa. We don't know.
