Yesterday, New Orleans did for the first time something it had done so successfully so many times in the pre-Katrina days. It held a championship sports event. You may have missed it but the San Jose SaberCats beat the Columbus Destroyers, 55-33, in the Arena Bowl (winning San Jose quarterback Mark Grieb and mother Shelly are pictured at right). For San Jose, it was its third title in six years. But the big news, I think, was that the game represented one more step for New Orleans in its comeback.
