You're confusing Post Defender with Help Defender. As a Post Defender, Hibbert's the best bet you have I think in the entire draft. As a Help Defender, you're underrating his reaction reflexes. He's gotten significantly better over the years. Exactly which games did you choose to watch anyways? Obviously not the latest ones.
People are becoming starry-eyed with the advent of the run and gun teams like the Suns/Raptors/Warriors, but there will always be a premium on the post. Lopez isn't a very good defender, nor does he have the understanding of the game Hibbert has. He's more mobile; so what? Unless you play at great speeds, it isn't going to matter.
Limitations in rebounding?
Whatever you say. Just for the record, no offense would be built around anyone short of a superstar. Hibbert's upside may not blow anyone away, but he's going to be a quality player in the NBA.
I watched Hibbert the last 2 games he was in. He's not a great rebounder.
I didn't say Horford was a center. He is a great rebounder.
Horford is a better
player than Hibbert. Therefore, I'd take him over Hibbert.
I don't agree on Lopez. I think he's a very good post defender, better than Hibbert, because he can move better than Hibbert. If I want a lampost at the center position I'd go out and get one - they must be pretty cheap to rent. I think Lopez has more upside than Hibbert - he's fluid in his offensive moves, he's getting better in his range, he *can* come from the weak side.
The bottom line for me is that Hibbert is a riskier pick than Brewer and Horford. Brewer is an All-Star waiting to happen. He shot 53% on 3 pointers in the last two years in the NCAAs. Defensive Player of the Year in the SEC. Bigtime pressure player. I think Horford is also going to be very solid, though I'm not as sure of his All-Star potential. He'd have to extend his range on his jump shot from 15 feet out a little further, but that's definitely doable.
I'm going to be surprised if Petrie picks Hibbert.
