Re: If your team doesn't win the Super Bowl, is the season a failure?
Salary Cap era in the NFL is different than the NBA. Every year, any team can win the super bowl (except the lions). You can't say that about the NBA.
And just because you win a couple of games in the playoffs doesn't mean you'll even make it back to the playoffs the next year.
So if you don't win the Super Bowl, the year is a failure. These days, you rarely see "building upon playoff success". Next year, you may not even make it back.
