Getting RJ and McDyess are definitely nice additions. I just don't see much depth in the team. You have Manu off the bench... and everyone else is pretty much crap. Hill might turn out solid, but that's about as far as it goes. The only other guys worth mentioning consists of Finley (broken down, streaky as ), and Bonner (LMAO bonner).
I think the Spurs are definitely top 3 in the west, but I don't think that they are unquestionably better than the Mavs and Lakers like some spurfans are saying. I think it could very easily turn out to be a classic dogfight at the top for all three of those teams. The key for the Mavs and Spurs however, is health. The key for the Lakers is to maintain the same hunger they had this past year.
