Given his age and hustle, I could easily see a young team throwing $45/3 years at Vanderbilt if he was a free agent right now. If a player could be making 3-4x more than they are currently making in a free market, then they are underpaid.
Vanderbilt is on a fantastic contract, is only 23, and has shown fantastic improvement over the past 4 years. Though infrequent he has added a 3-ball, has improved a lot as a passer and court vision, gives his all. I understand not liking a Draymond comparison but saying he isn't extremely underpaid is just dumb.
