Not only was it a foul, but Dirk traveled with about 18 seconds left (could have left SA with more time to get off a shot at the end). This game was further proof that the kid gloves come out when the big German is in town (in SA or Phoenix) - Dirk has numerous phantom fouls per game, so what if Duncan gets one that an actual MVP winner deserves!!! I wish someone would take the time to find such stats, but I'm sure Dirk is the first 3rd place MVP vote getter to garner more sympathy from the refs than actually winners. I surely wish Cuban would send clips of this game into the league; since he cares so much about the quality of the officiating, it would only be consistent.
One positive thing that Spurs fans can take away from this is the extreme class exhibited by the team and coaching staff. When Duncan and Finely were (appropriately) irate at the no call, Pop just walked over and patted his boys on the back and calmly led them into the locker room. Of course, he did pause to look at the replay one more time to confirm how bad the call was before he walked to the back. Imagine if Baby Dirky or Jason "the Choke" Terry had been in Finely's position, Cuban and Avery (who is slowly becoming the biggest pussy coach in the league) would have run onto the floor, jumping and screaming and berating the refs and then AJ would complain about them more in the press conference and Terry would have punched all 3 refs in the balls. This class is the reason the Spurs have championships and the Mavs don't and never will.
