The Mavs already have the guy -- got him for a future #1 pick. But the Mavs WANT O'Neal -- he's the piece that would send them over the top and make them a contender (lord knows the Mavs have the shooters to create space for Shaq -- they certainly won't miss over and over again). The Mavs have struggled in three areas: 1) post offense, 2) post defense, and 3 rebounding. Shaq shores up ALL three of those areas. Imagine the kind of spacing that Shaq would give the Mavs -- with Dirk, Finley and Daniels to knock down open shots -- opponents would be hard pressed when it came to doubling. Shaq is a very good passer -- so is Finley -- this team would go to a leading candidate even with dumping off several of it's players to make it happen. And Cuban wants a championship TODAY -- not tomorrow so this trade just makes a LOT of sense for both teams.
