I believe that last year's team was a playoff team, if the injuries had been less impactful.
Losing every single CB on the team and every single LB on the team, which happened to be your two weakest position groups to begin with, set last year's team up for failure.
Stay reasonably healthy, this is undoubtedly a playoff team.
Get some good coaching from Nolan/Klein, this is a very "tough out" type of playoff team.
Create some turnovers in the playoffs? Well then, this could very well be a Super Bowl team.
