Co-sign Paul. You saw what the Giants' defense did to Favre in Green Bay in the NFC Championship. They got to him, rushed his throws and picked him off 5 times. A strong defensive line that gets a lot of pressure on the QB will cause Favre to make bad decisions. Favre relies a lot on his athleticism, he's been called a gunslinger and that's exactly what he is. Rushing a gun slinger forces him to throw into confused or problematic coverage. Leaving him open allows him to take his time and rifle the ball.
