Fixed so your comment was more accurate.
But yeah, how well you play college basketball has something to do with your NBA game, but not everything. Adam Morrison wasnt a great NBA player, was he? He played hard and stuff too.
None of that means I don't like Sabonis, he is an OK prospect in my eyes, but I wouldn't take him over Jones/Davis and I'd probably take Skal over him. I'd draft him ahead of Thon though.
If you go by potential based on age then Sabonis should actually have more as he is actually younger than Skal.
