Those teams never tanked on purpose to get those QBS.
Rams were a dumpster fire, Eagles traded up, and Colts got Luck because Manning got hurt and that team was just brutal.
Losing games vs tanking on purpose is apples and oranges.
I for one don't even care if the Bills lose the rest of their games because to your point it would get them a higher pick.
But as a coach, you cannot do that to your locker room. You just can't. Unless you want to lose respect from every single player
