The organization up top, the FO, wants to tank. The players and coaches don't and it's silly to think otherwise. Every week they are playing for their jobs and future paychecks.
You think Flores puts in Fitzpatrick if he doesn't want to win there? He could have easily left Rosen in and called it developing him, no questions asked, and lost by multiple scores. He didn't, he and the players wanted the win.
Luckily the FO has done a good enough job on their end of securing the tank that it doesn't matter. That's the proper way to do it.
