I wonder if it would become like games we typically see the last week of the season, where the starters often sit.
No way you get a guy like Kawhi playing in this, and guys with $100m+ contracts and big endorsement deals aren't going to care, I'm sure most of them would rather have a nice little break from action.
But then you have your Tremont Waters, Shane Larkns, Phil Presseys, Javonte Greens, etc. An extra million would be a big deal for those guys (plus more if they get the shares from the stars/vets who choose to sit too). So you want some extra cash Tremont? Well you're going to have to go out there and earn it.
The way to get it to work is to really up the ante, like all the luxury tax payments for that season go to the winning team (which would probably further increase super teams and give the odds to big market teams, but would make for a high stakes game between Brooklyn and LA).
