I agree. It's mind boggling to think people would be fine with intentionally taking an L in a conference game. The players wouldn't want that. The coaches wouldn't want that. It accomplishes nothing positive and in the end will just be a negative in multiple ways. If players really need rest that badly then Head Coach Geno can and probably would do a few easier practices between games.
Besides, what does it say to bench players to essentially be like "we're just giving up on winning so it doesn't matter if you suck".

If you're a bench player, you should be looking at a game like this and thinking you want to be the next reliable player up who Geno can sub in when necessary.
This isn't like the later Stewie years where the starters can play 10 minutes and the game is done and dusted. The starters need to be out there and it will benefit them and everyone else in the long run. I bet if you asked any of the starting 5 if they had wished they'd sat out so they could be rested, they'd all disagree. They're all fiercely competitive. They want to be out there.
