Jets at Bills

TV: Sunday, 1, CBS (Kevin Harlan, Rich Gannon, Steve Tasker)

The matchup: After plummeting from 10-6 to 5-11, the Jets jettisoned several aging veterans and are in total rebuild mode. There could be a dozen new starters in the lineup for the opener, with eight of them in either their first or second seasons. Despite the youth movement, coach Todd Bowles has chosen journeyman QB Josh McCown to run the offense after second-year QB Christian Hackenberg bombed out and Bryce Petty was injured in preseason. ... Under rookie head coach Sean McDermott, Buffalo also is building for the future and could field a dozen new starters, but third-year starter Tyrod Taylor appears ready after being cleared from concussion protocol. McDermott is hoping a switch to a 4-3 alignment will boost a Bills defense that slipped from fourth overall in 2014 to 19th in each of Rex Ryan’s two seasons as head coach.
