A football season is a mini lifetime. It's amazing to look back on it and see how much has changed.
• Remember when the Falcons were locks to make the playoffs?
• Remember when Ben Roethlisberger got hurt (several times) and the Steelers appeared to be finished?
• Remember when Russell Wilson was having a hard time living up to his new contract?
• Remember when the Cowboys were 2-0?
• Remember your preseason Colts Super Bowl prediction?
• Remember the 1-5, utterly hopeless Kansas City Chiefs?
• Remember wondering if anyone could beat the Patriots or Packers?
• Remember when Cam Newton was just another young quarterback with something to prove?
A lot has changed in the last four months, and these final report cards reflect those changes. While the grades are weighted slightly toward second-half accomplishments, the report cards remember when the Rams looked like a playoff team and the Texans didn't.
The grades are based on the GPAs that have been calculated all year, but they are curved a little to prevent the whole league from falling somewhere between C- and B- (as happens when you collect 17 sets of grades). Week 17 results count for a little, but not as much as other weeks.
These grades are meaningless now that the playoffs are here. But then, they were always meaningless. Think of this as a 2015 yearbook, a chance to reflect on just how many ups and downs every NFL team experienced since the start of September.
