Reggie was great but he wasn't a lockdown defender. He used his length to block shots. He was a great outside shooter who rarely took threes. I've read that the summer he died, he was working on adding the 3 to his game. His game was mainly stopping on the dime off the dribble and pulling up for the jumper, with a little slashing to the basket and post ups mixed in.
Odom is much more of a playmaker and also a much better rebounder than Green. I know its early, but I don't thik Green has an assist yet. However, like Odom, he is a solid, well-rounded player.
I am not a huge fan of Green's upside, meaning I don't see all-star potential, but I think he can be a very good bench player who plays alot of minutes. Hopefully I'm wrong and he'll be better than that.
