You both realize he led college basketball in rebounding too? Millsap is much more stocky than Basabe at this time but as others have said Basabe is only a Jr.
I saw a fun fact a few years ago that every player who led the NCAA's in rpg made the NBA the next year. I am not saying Basabe will do this but it is some food for thought. If Basabe is leaving early he is doing it with some awful advice.
