PITTSBURGH STEELERS (13-4)
OPEN CAMP: July 26, Latrobe, Pennsylvania
LAST YEAR: Steelers won second straight AFC North title and third in four years as "Killer Bs" trio of QB Ben Roethlisberger, WR Antonio Brown and RB Le'Veon Bell received plenty of help from rookie WR JuJu Smith-Schuster and defense that gave up big plays but also led NFL with 57 sacks. Still, Steelers had trouble when pushed by quality teams. They let second-half lead get away at home against New England, loss that cost them home-field advantage in playoffs. And they couldn't find way to beat Jacksonville, which won at Heinz Field not once but twice, including divisional playoff upset in which seemingly offensively challenged Jaguars put up 45 points.
