i honestly doubt a chris simms or tim rattay signing will mean if cassell has a bad game he's yanked.
Thier insurance against another season ending injury (to cassel), i would actually expect o'donnal to be next in line if cassel absolutly stinsk (which he wont, he'll manage)
i mean, the guy isnt rex grossman, and he leads a high power offense.
For the regular season, he'll be fine. the injury to tom actually, in my mind, places waaayyyy more presure on the defense, since now they have to think of it like 2001, where every point matters, not like 2007, where they could give up 24 to a bad team, since the offense was going to hang 32+ on average.
