‘The more significant hire – and one that will go a long way in determining Marrone’s success – was Pettine, who was the highly regarded defensive coordinator of the Jets the past four seasons. His units ranked in the top 10 each of those seasons. Now, admittedly, some of the credit for New York’s success on D belongs to the Jets defensive-minded head coach Rex Ryan. But Pettine spent 10 seasons working under Ryan (first in Baltimore and then, New York) and has learned his lessons well.’
