It’s not remotely unimaginable...already 75% of the way there, and he’s spanked Tennessee all 3 years. If he stays at Vandy, you can make book on him beating Tennessee yet again.Mason could pull off the unimaginable, beat Tennessee four straight years. He'll if he did that they should build him a statue and rename the stadium.
Why would he take the Colorado job? Money maybe, I see no other reason.
