From the excellent Tuesday Morning Quarterback column by Gregg Easterbrook-
"The Jets have spent their past six first-round picks and eight of their past 12, which covers the past 10 years, on either a defensive lineman or defensive back. Yet their defensive performance has gradually declined since their No. 1 finish in 2009. Then, Rex Ryan's all-out exotic blitz philosophy was distinctive. Now most NFL teams show what were once viewed as Ryan-style crazy blitzes, while what was distinctive in 2013 was Seattle's conventional defense with a straight four-man rush. In a globalized economy, clever ideas get replicated fast. Ryan's way of playing football, which once seemed potent, increasingly looks tired."
