I'm pretty sure Rouge was made up of a lot of Louisville girls who were able to super senior. I don't know if it was ever intended to be more than a one season team, because they weren't around last year either, to my knowledge.
I think for a gym like GymTyme, that is so reliant on the college students in the area for the older teams, it can be hard to keep teams consistent from year to year. Their ability to make multiple senior aged L5 teams might hinge largely on the amount of super senior eligible freshmen (+ super super senior eligible sophomores) entering Louisville (and UK, if any athletes commute from Lexington). I'm sure they have high school aged L5 athletes, but are there enough to make more than one competitive senior L5 team every year? I'm not from the area/associated with GymTyme in any way, so I really don't know, it's just a thought.
