Give me the W's and L's that's the only stat that matters.
W's and L's are crucial to figure out if you're have a winning, average, or losing record. To find out why you have a certain record in the off-season, you must be able to evaluate each player individually so that you may make the necessary changes in the off-season to improve.
If the team trots out the worst defense in football and refuses to run the ball, despite it's effectiveness, replacing your QB because they threw that last game away and that ninth win, will probably result in another last place defense and lack of running game the very next year. Guys like Manning and Brady have consistently gotten help through either defense, the run game, or proper scheming and game planning to mask the flaws in their offense or defense(coaching). They weren't all all-stars, but there was support. Our QB has like 1 yr of that and another where it almost worked out.
Your quickest way to recovery is to probably improve the defense and run the ball more and not require your QB to do something no other successful QB in the league is doing and then bashing him for not living up to your impossible standards, especially when the QB is not the best QB in the league and is not paid like the best QB in the league. When your defense can't keep the lead, and your coach decides to give up some wins for the lolz (this has to be some kind of trolling) that 8 win season is probably an 11 win season on those improvements alone.
