The Detroit Lions were viewed as a team on the rise after their 10-win season in 2011, which included a postseason appearance.
However, the team struggled mightily in 2012 due in large part to a lack of discipline and maturity under head coach Jim Schwartz.
Ndamukong Suh has not lived up to his top draft selection as a whole due to his inability to be a consistent pass-rusher and anchor a veteran defensive front that struggled this year.
The development of Matthew Stafford is a cause for concern, as he threw for 20 touchdowns after throwing for 41 the previous year. Concerns about him throwing off his back foot, along with his knack to throw costly interceptions, came to fruition for the Lions this year.
Calvin Johnson had a splendid season, but his success was overshadowed by the fact that he is a part of a 4-12 team.
