FG doesn't do anything for them at this point. Might've gone for it if they hadn't missed the FG earlier but whether you're trailing by 11 or 14 its still a 2 score game.
Corner has been their weakness for a couple years now, they've got a couple kids with the potential to be above average but its still just potential. They're set at safety at least with Meriweather and McGowan.
It takes time to completely overhaul the defense, going from the Harrison/Bruschi/Vrabel/Samuel/Seymour group to a bunch of kids like Mayo, Meriweather, Butler, Wilhite, etc.
