Pettine's contract with the Jets expired after the season and he reportedly wanted to stretch his own wings outside of Rex Ryan's defensive shadow. So he makes the lateral move inside the division and joins new coach Doug Marrone's staff. Pettine's unit ranked eighth in 2012 despite losing Darrelle Revis for the season in Week 3. And in the three years before that, the Jets' defense was inside the top-five each season. The Bills, who have bounced between a 3-4 and a 4-3 over the last two years, have some serious building blocks on defense in DE Mario Williams, DT Marcell Dareus and CB Stephon Gilmore. Pettine figures to bring an aggressive, blitz-heavy scheme to Buffalo.
