The thing is, there are skills that work great in college, and there are skills that work great in the NBA. There are players who are awesome in college (think Madsen, Adam Morrison, Trajon Langdon, Michael Bradley, all the way back to Big Country Reeves), who flop in the pros. That's because if you're skilled in college you can be a good, even dominant player in the NCAA. But in the NBA you have to be athletic, and if you're a power forward smaller than 6'10" or a center smaller than 7'0" you have to be REALLY athletic.
Love looked like a really good college player on Sunday, and most other days he plays. Most of the time he's the biggest and strongest guy on the floor, he has good hands and is good at getting rebounds. I saw what you saw in that respect -- a big who was cleaning up.
But when you're looking at how someone's skills are going to translate to the NBA, here's what I see: someone who is definitely not 6'10" and probably isn't even 6'9". A guy who is earthbound and can't jump at all, and who isn't quick by any stretch of the imagination. Who isn't a great man defender or shotblocker.
The skills that Love excels at (rebounding, shooting) aren't going to be available to him in the pros, when he's not the biggest guy on the floor and he's going up against guys who are bigger than him and more athletic than him.
In college you can get away with slow and skilled, in fact you can be quite good. In the NBA these guys get killed. Mark Madsen, Michael Bradley, Araujo, Haislip... I mean, these guys were all awesome in college and they were major flops in the NBA because they just weren't athletic enough.
Now, take Thabeet. The reason I'm so high on him is that the skills that he has will translate even BETTER in the NBA than they do in college. In college he's playing with guys who don't get him the ball (and I've seen him be quite good at getting the ball up and in when he gets it in the post), he's guarding guys who are much smaller and quicker than him and so he's often in foul trouble (which wouldn't happen as he's going up against real centers in the NBA), and the things he excels at (shotblocking, rebounding) WILL be available to him in the NBA because he has NBA size and athleticism.
If you're judging just on game impact at the college level -- yeah, Love is more dominating. Thabeet is still a project. But if given the choice, I'll take the guy who has elite NBA level athleticism over a guy who doesn't. There's always a place for guys who have great size and athleticism for their position. Not so much guys who are "skilled" and unathletic.
