Winning--in professional sports, certainly--is everything. Playing well consistently is an important component and contributor to winning.
"Everything" and "important component" are not the same thing.
So it's not important to be consistent all the time?
Sounds like you are saying that if a team is going to lose they might as all look bad doing it. No wonder some are not disappointed with the way the offense played this year. Hey, if the defense stinks they might as well stink too right? Good thing they didn't play that way last year.
