Yeah, the players and coaches played the Raiders tough. They are clearly trying. They had a goal line stand earlier.
The way you tank is by getting rid of talent. There's no incentive for a player to not try his hardest. He would be putting bad tape of himself out there and that could lead to missed opportunities. Similar with coaches. Coaches almost never survive a tank, so why would they play along and assist in themselves getting fired?
Now, when it's clear you suck I can see the effort of players and coaches waning because then all you have to play for is pride, and sometimes that isn't meaningful enough. But they are too competitive to go out there and try to lose.
The Jets suck. Their players and coaches aren't motivated or happy, I'm sure. The writing is on the wall that everything is about to get blown up.
