I don't get the urgency to extend Barnes either, but I'm not privy to the conversations being had behind the scenes. I'm more focused on Vitello. It is going to escalate the salary gripes about Barnes' by our fanbase though, considering the first round exit this year.
I will say, it can easily be spun as a good thing (i.e. committing to the program), and Barnes' is recruiting at a level never seen here before. Money doesn't seem to really be an issue at Tennessee, so it's probably not that big of a deal if true.
