The original "tweeter" is a guy from the Tennessee horde, so to speak. Could be Walz is floating the idea to push for a raise, or just to test the waters. Could be Tennessee is wooing him, but getting him to the alter may prove more problematic.
I feel sorry for Holly. She's not even been "fired yet". No matter what you think of her coaching, she's a human being who gave blood, sweat, and tears to that program. If this is how they take care of replacing her, shame on Tennessee. Holly deserves better. Fire her first, if that's the plan, and then go after the replacement. It's just common decency.
And by the way the timing makes no sense. Why would Walz even be talking to them? Isn't he preparing his team for the Sweet 16 with the hopes of a run to the NC? I get that people can multi task, but an ethical person would say "I will discuss when my team's season is over".
