Detroit Lions – 2012
The Lions entered 2012 off the back of their first winning season since 2000. It’s no surprise that their delirious fanbase hoped that they’d go even further this time. But Detroit regressed despite being one of the most hyped teams of the year. Matthew Stafford was the reigning NFL Comeback Player of the Year but relied too heavily on Calvin Johnson.

Meanwhile, their defensive line wasn’t the same despite being one of the league’s best in 2011. Several serious injuries occurred at key points of the season. Titus Young was a serious loss while there were off-the-field problems too with arrests. It was a dismal year but that sums up Detroit (via Sportsnet).
