The New York Jets have used a 3-4 defense for much of the past decade, but because offenses are constantly evolving, the team's defensive coaches want to go to a 4-3 base because of the spread offenses, especially in the AFC East.
"We might not play a snap of base defense in a division game this year," Jets defensive coordinator Mike Pettine told the New York Daily News. "If it's five snaps a game, that's probably a lot."
Using a 4-3 defense will make for a more aggressive gameplan and puts more of a focus on stopping the pass than the run. In three seasons under head coach Rex Ryan, the Jets finished 18th, seventh and 17th in the league in sacks.
