What do you think of Oprostaj's idea of trading JT? If Griffin is the complete PF, maybe instead of trading down, we just trade. Say JT for the 5th pick, and take Teague.
I think it would be really risky to trade a relative sure thing for someone who's somewhat of an enigma. If the difference were huge between Griffin and Thompson to the point where it's a no brainer I'd say yeah, sure, draft Griffin and consider opening up a spot for him. But while I like Griffin's athleticism and the way he attacks the rim, unless he surprises me with his height in the measurements, I really don't think his ceiling is that spectacular.
I don't think Thompson is the next Chris Webber, but he's at least projecting to be a really good 6'11" strong rebounding power forward with some skills inside and out.
Griffin on the other hand.... I'm still not convinced he's going to be Kenyon Martin without the defense or anything significantly more than David Lee. He's got the potential, but it's going to require him to seriously develop his offensive skills and I just don't know about his coordination.
This is perhaps one of the worst years for college bigs I can ever remember. There are only two quality seven foot center in college right now projected to go in the first round, Thabeet and Mullens, and Mullens is a total work in progress. Not to mention that there are hardly any other power forwards projected in the first round. To think that Stanford just last year had two quality centers on the SAME TEAM, and it goes to show how weak college bigs are right now.
All of this is to say that I think Griffin is benefitting a great deal from a lack of real competition. He's just not facing anyone who is close to his size and strength, but he's going to have a major challenge when he reaches the NBA. He hasn't developed his offensive skills, he is not a shotblocker at all, and I don't know that he's tall enough to have a commensurate impact in the NBA. When you compare him to someone like Amare, he's just not built like that, and I don't think he's as explosive, and Amare still can do things like put the ball on the floor and hit outside jumpers.
Thompson has his limitations, but at least he's 6'11", and he looks really promising. I doubt personally he'll be a superstar or even a star, but it's not hard to see him holding down the starting PF on a good team for many years.
So my feeling remains: if we get the #1, either Petrie should just draft who he likes, even if that's Griffin, or trade down. But I don't think it's a good idea trade a young promising player for an unknown draft pick.
