such a switch is going to require to some serious FA pickups in the D-line.

Defensive Ends
Johnny Jolly, GB, 27 years old
Marcus Spears, Dallas, 27 y/o
Richard Seymour, Oak, 30 y/o
Jarvis Green, NE, 31 y/o
Travis Kirschke, Pit, 35 y/o
Nose Tackles
Vince Wilfork, NE, 28 y/o
Aubrayo Franklin, SF, 30 y/o
Casey Hampton, Pit, 32 y/o
Ryan Pickett, GB, 30 y/o

some of these guys will be re-signed, but not all. It seems doable if we want to.
