Oakland Raiders: Why 2011 Season Was a Success, Playoffs or Not

What qualifies as a success in the NFL?

Is it a lovable loser finally making the playoffs for the first time in 11 years (The Detroit Lions)? Is it an unorthodox quarterback revitalizing a moribund franchise and becoming the most polarizing figure in sports (Tim Tebow)? Or is hoisting the Lombardi Trophy after the season’s final game the only true measure of success in the NFL?
