Wait, you're saying the Jets are built from free agency?
Revis is home grown talent. He just grew too damn much. He became extremely expensive and we let him go after the injury. Coulda had him back last season (and prevented another Pats SB), but Idzik was an idiot.
Beyond that, let's just look at the D (one of the best in the game).
Dline: Wilk - drafted, Harrison - undrafted but here since a rookie, Richardson - drafted, Williams - drafted
LBs: Harris - drafted, Davis - drafted, Mauldin - drafted, Coples - drafted, Pace - FA but been here a while
Secondary: Revis - drafted, Cro - FA but been here a while, Skrine - FA, Pryor - drafted, Gilchrist - FA, Milliner - drafted
Not really built via free agency at all.
