Not 1, not 2, but 3 sub .500 teams in the top 10. I know everyone was expecting the Cards, Panthers, and Bengals to be really good this year... but they haven't been. The Cards lost to a really good Pats team, beat a mediocre Bucs team, and got embarrassed by an embarrassing Bills team (that you have ranked in the 20s). The Panthers have a bit more of an excuse as their losses have been to mostly good teams (the Broncos and Vikings) but I am still not buying a #5 ranking for a 1-2 team who's only win came against a horrible 49ers team. Lastly you said it all about how the Bengals have performed so far this year. These are not good teams this year, shouldn't their ranking reflect that?
While your brief analysis of the Panther's Oline has a lot of truth to it, I'm not sure it's yet fair to say that their is a problem in the 2ndary. The rooks are playing pretty well and definitely aren't the problem. Another is that they can't get a pass rush because the QBs are having success throwing the ball for short, quick, Brady esque passes, but when throwing deeper, the interior rush at least is getting there, and the corners have been impressing. While they are no Norman at this point, I can say that they are one of the few bright spots so far. The main problem is that the Oline can't block, and special teams can't tackle.
Limited experience dropping into pass coverage - liability
Tendency to quit if play is away from him
Still a work in progress after declaring a year early
Suspended by team for two games in 2009
Summary: Justin Houston caught a break when Georgia went to a 3-4 defense this past season. It gave him the opportunity to showcase his ability to stand up as a pass-rushing outside linebacker. Teams running a hybrid scheme changing fronts will find him particularly appealing. More than any other trait, Houston's ability to get after the quarterback will put him on the radar early in the 2011 NFL Draft. On the down side, he might be limited to being a situational pass-rusher in the pros unless he can improve his all-around game.
Player Comparison: Terrell Suggs. One of the reasons I would like to see Houston drafted by the Baltimore Ravens is that Suggs is a similar player, which could expedite Houston's development. Houston's faster 40 at his Pro Day helped this comparison because the height/weight factor is already there. It is always uneasy comparing an unproven college player to an elite NFL talent, but Houston has shown signs of having similar qualities.
