Just a silly idea, what about a league where any team that finishes under .500 fires its owner? Most owners wouldnt last for long but that would be the point. Stick around for five seasons and you would have some bragging rights. You would see lots of big contracts, trading and crazy moves. Not for the faint of heart.
It would have to be private to enforce those rules. I dont know that WIS (or anyone else) would be into a league with about 50% turn over every season. But it would be unique.
