If that wasn't a big enough turnaround, the team followed that up with a 10-6 record in 2011 to make the postseason for the first time in over a decade.
The Lions are on the rise, there is no doubt about that. The team's defensive backfield, however, remains the biggest issue on the team (besides off-field issues, that is) and seems to be the one thing holding them back from being a Super Bowl contender.
The Lions are already a playoff team, they just need to take another step. Many people aren't giving the secondary any credit, but they aren't as poor as everyone thinks.
