Houston is second-best, though it’s hardly cause for celebration. The Texans got excellent production and leadership out of strong safety Bernard Pollard when he joined the team and settled things down. But Eugene Wilson didn’t make it through the season. He seems less than an ideal match for Pollard, but the Texans don't have any good alternatives unless Troy Nolan, a draft pick from last year who was hurt, can step up.
Tennessee’s Chris Hope and Michael Griffin were Pro Bowlers two years ago. Last year they were quite shaky. Hope is aging and often seemed indecisive in 2009. He took some blame for not getting on Griffin enough, allowing their friendship to get in the way. Griffin admitted personal stuff was getting in the way last year. Can he compartmentalize better? That may be the biggest question for the defense.
Jacksonville has no real idea if Reggie Nelson will bounce back -- he also played some bad corner and nickel last season. Presuming he starts, Gerald Alexander is most likely the other guy, but Sean Considine and Anthony Smith are in the mix. Some scouts say all four are merely “guys,” a way of saying the team can do better. Second-year man Courtney Greene could earn a chance.
I stack them in that order, but after the Colts, it’s moveable ground based on camp and preseason performance. If things don’t get better, however, look for Manning and Schaub to shred the deep middle.
