There is something similar to that around here. If you win your division, then you qualify for regionals. If your team doesnt return for the next session, you automatically forfeit your qualification. Also, if your team does return for the next session, and you dont keep your winning percentage above 50%, you forfeit your qualification.
My take behind this entire thing is that the LO doesnt want to miss one penny of that money coming in, and he wants to make it very hard for a team from his division to go to Vegas.
We have some similar restrictions here, as well, and I understand where you're coming from. And I agree with you, the LO's are most certainly interested in maximizing their income, and to an extent there isn't anything wrong with that.
I can understand the LO expecting a team that has is eligible for their Vegas-qualifier to continue playing. The LO is going to be paying to send them to Las Vegas, they ought to continue in the league. It is also an anti-sandbagging issue, as well. If you don't play, you can't "go up", can you?
The idea about keeping the team winning percentage above 50% after you've qualified is also to limit sandbagging, i.e. throwing your matches once you're qualified, to keep your handicaps down. Our bylaws state that a team
"can" be disqualified if that happens, meaning it isn't automatic, and that the LO has some recourse if he truly believes the team is dumping. Yet if they are having a bad run, he doesn't have to automatically forfeit them. Last year my team was close to our LO having to make a call on us, but we ended up just over 50%. Trying all the while, mind you. (If you don't believe that, I can tell you we just finished tied for 1st place this last session, while we were already qualified. We certainly do "try", all the time.)
It is interesting to see and hear some of the different bylaws throughout the country. Ours don't seem to be too far off from the standard National rule set, fortunately. That area that allows jump cues... that's a drastic change from national. As I said, interesting...
