I don't know why everyone's underestimating the Browns.
They have the potential to win 8-10 games if a few things fall right for them. If Bentley can play this year, an OL of Thomas, Steinbach, Fraley, Bentley and Shaffer match up with almost any OL. If Lewis regains his form running behind that line, eight in the box won't really matter.
Defensively they really only need the DL to step up because the LBs with Wimbley, Jackson, McGinest... are upper level and the secondary is underrated, especially if Wright can step in.
People keep talking about 0-6 in their division but seem to forget that Cowher's gone, the Ravens are getting old in a hurry and lost their best defensive player from last year and half the Bengals roster is in jail plus they lost their best OLineman.
As Edwards and Winslow continue to develop, I can see a Brees/Rivers situation develop with Frye/Quinn.
