In 2012, the Lions were a statistically impressive team.
They broken some records and led the league in some key areas. They also finished 4-12, largely due to injuries and a lack of balance.
The Lions can't really do anything about those injuries (other than improve their depth), so what's left is to become more balanced. And since it was partially imbalance that brought such huge statistical numbers last season, it stands to reason that some of those numbers will have to decline for the Lions to play better as a team and become more balanced.
Of course, that doesn't mean these guys are going to play worse. It just means their individual stats won't pop off the charts because their teammates are picking up the slack, which is a good thing. So, don't think this is a prediction of five players' falls from grace. In many cases, it's a discussion of who can play more efficiently.
Here are the five players who must be less impressive in stats for the Lions to become more impressive in record.
