Defensive tackle is a thin position right now because of the uncertainty. The Bears have to rely on an oft-injured former star, an inconsistent former second-round pick, two rookies and a veteran backup coming off a torn ACL.
Jeremiah Ratliff heads a group looked to to help reinvigorate a defense that was dead last in stopping the run last year. Ratliff is a four-time Pro Bowler who has only played in 11 games over the past two seasons.
Stephen Paea is coming into a free-agent year, and the Bears still don't know who he is. At times, he looks like a solid nose tackle and then other moments he completely disappears.
Will Sutton and Ego Ferguson were talented guys in college, but do they have the makeup and work ethic to make it in the NFL?
Nate Collins should be fine coming off his knee injury, but, at best, he's still no better than a rotational player.
In order for this unit to perform well, the Bears need Ratliff to stay healthy, Paea to be motivated by a potential new deal and two rookies to be ready to contribute right away. That's asking for a lot to happen all in one season.
