"I think that in a growing league it's almost going to be year-to-year sort of looking at how you do it," Hanauer told the Seattle Times. "There's a competition committee meeting coming up real soon. That'll, I'm sure, be on the agenda."
Hanauer said the league is always open to changes.
"We're a small, growing business," he said. "We want to listen to our customers, and we want to provide the best product possible with the constraints and realities that we deal with."
