Melo won a championship Durant lost in the 1st or 2nd round. I don't see how you could put Durant's college career ahead of Melo's. Davis certainly I wouldn't argue that, much . Of course Melo played for a HOF coach and had a better team around him than Durant did but still Melo put up something like 52pts, 25r, 8a in the two FF games. That's pretty epic.
Durant had 30 and 9 in their NCAA loss.
