I still think we need another big. Chukwu and Coleman are centers. They're not moving too far from the rim. And 2 centers isn't exactly an embarrassment of riches. I think Chino's back to give us a 3'd guy in the middle.
As I understand, Thompson's 6'9-10. So he's probably looking to backup PF to play on the other side of the rim from center. Yes TR plays here also, but it'd be good to have an alternative to him. Because (without G) Lydon's probably going to play the 3, backed up by Moyer (who seems to be in the Billy Owens mold).
I've been posting about the front court puzzle for a while now ... very intriguing, especially the 3/4. Lydon there gives us a second big forward, who can shoot from the outside and drive. My assumption has been that Moyer (6.8 and probably NRFPT) would back Lydon up at SF, although I don't know his game as well as others. I've pegged him as a SF/CJ fair type of player, which would be consistent with size. Whereas , Thompson would be a 4. backing up TR.
