Looked like an option route, Favre misread the D and went deep with it,but Cotchery saw the defense and went inside, Favre's fault i think, he went offhis initial read instead of looking for the WR.
I said it when the trade happened- if Favre plays like he did in 05 and 06, the Jets will have wasted a year when they should have drafted a legitimate QB (don't tell me Clemens is one) and develop him. Might as well have gone with a cheaper option that wouldn't have cost a draft pick.
