WHERE TOP DEFENSIVE ENDS MIGHT MAKE MOST IMPACT

Jacksonville Jaguars: Coming off a 3-13 season, defensiveminded coach Gus Bradley needs a diverse defensive end-outside linebacker who can generate double-digit sacks.

New York Jets: First-year coach Todd Bowles has remade the squad’s secondary with prized free agent cornerback Darrelle Revis, Antonio Cromartie and Buster Skrine. Still, the Jets are lacking an elite, passrushing defensive end who can win on the edge and ease doubleteam pressure on Muhammad Wilkerson and Sheldon Richardson.

Chicago Bears: Defensive ends Lamarr Houston and Willie Young are coming off knee and Achilles injuries, respectively, which makes them question marks. With Jared Allen having turned 33 two weeks ago, new coach John Fox needs to get younger and faster at the defensive end position.

Atlanta Falcons: The 6-10 Falcons tied for 31st in the NFL with 22 sacks in 2014. New coach Dan Quinn, formerly the Seattle Seahawks defensive coordinator, preaches an attacking defensive mind-set that could use a boost from a dynamic edge catalyst.
