The new arena will have the same problems hosting minor league professional teams the old one had, a three weekend, two week, rodeo in late January and February, smack in the middle of the winter season. Fort Worth has always sided with the rodeo when it came to upgrading and repairing the arena, leaving most minor league team's management in anger. That's why all have left.
The Spurs never seem to have a problem with this every February and that's one of the top NBA organizations.
I'm sure minor league teams could work out the same thing.
