It's time for football again, and time for Doug Farrar of Sports Illustrated and Greg Cosell of NFL Films to preview the 2015 season, division by division. We start with the AFC East, a division with all kinds of questions: Can Jimmy Garoppolo pick up the slack for the Patriots during Tom Brady's suspension? Will improvements on defense and Ryan Tannehill's development make the Dolphins the team to beat? And can the Jets and Bills overcome their obvious quarterback issues with great defenses? Greg and Doug break it down schematically as only they can.
