Yeah, the secondary worries me but I think there's enough talent and depth on the line to be at least serviceable. Hopefully Marinelli is as good as everyone says. The linebackers do not worry me at all though--I think it's a top 5 unit in the league with the addition of Pisa. He's just a huge improvement over Hillenmeyer. Briggs and Urlacher are still among the best players at their respective positions. This defense is serviceable to above average. But even with Cutler, this team isn't going to the Super Bowl unless the offense or defense is top 5. I don't necessarily disagree but I think if you can control the ball, force turnovers, or get great special teams play you can be a SB caliber team without one unit being a killer.
