I really like Neal. He adds another dimension that the Spurs haven't had in a few years.
One thing I've noticed is that the starters are playing horrible defense. A lot of times it's been the Spurs bench that have either extended a lead or shorten the other team's lead. I really like the lineup of Anderson, Neal, Tiago/Duncan, McDyess and Manu/Tony. They can really stretch the other team's defense while playing, IMO, the best defense out of any Spurs lineup.
The one thing I have noticed however, is Hill's lack of confidence. He just doesn't have it right now. I think it's unfair to play him at the 1. He's most effective with a play maker beside him.
IMO, this is the Spurs' deepest team in the Duncan era.
