http://msn.foxsports.com/nba/story/5873026 The Dallas Mavericks added free agent forward Devean George to their minor makeover, giving them four new veterans on the roster, along with the dispatching of three others. What this really means: The Mavs were within six minutes of taking a commanding 3-0 lead in the NBA Finals this season before falling into choke mode. So close were they, it figured to be an off-season of tweaking. But what exactly have they accomplished by brining in George, Anthony Johnson, Greg Buckner and Austin Croshere in lieu of Adrian Griffin, Darrell Armstrong, Marquis Daniels and Keith Van Horn? Not much. In fact, the crew brought in is amazingly comparable to the one let go. Soon enough, we'll find out the ramifications of last year's collapse. Word out of Dallas is that Don Nelson is finally severing his ties from the organization rather than bilking owner Mark Cuban out of more money for hanging around. What we really need to know is how this all affected young coach Avery Johnson and his three key players ? Dirk Nowitzki, Jason Terry and Josh Howard ? with the way Cuban was so embarrassingly over the top in his profile as the Mavericks took the series lead. The moves in and of themselves didn't mean much, and they still should compete for the Western Conference title again ? but are they as solid as the San Antonio Spurs? Don't count on it.
