To be fair... you are telling me the Jets wouldn't try to win against the Jags knowing they get Trevor Lawrence instead of Zach Wilson. The Commanders wouldn't try to beat the Bengals to get Joe Burrow?
im sure the GMs would love it...
but what incentives do the players have - half of them will be out of contract and therefore won't want to risk injury, another bunch of them will be on long-term deals and won't want to risk injury, if your team was bad enough to be in that position in the first place it may well be likely that you've already had your coach fired or is literally the walking dead at this point
and contractually those players would be getting the "extra game" rates too - which for most of them will be less than their normal per-game salary too
in theory it's a fun idea - but no way the NFLPA would ever do it unless there were significant financial implications
