Buffalo Bills remain in flux in their secondary

Ryan Tannehill is set at starting quarterback, but his backup is undetermined.

Buffalo Bills: The Bills remain in flux in their secondary, just days before their season opener against the Baltimore Ravens. Head coach Sean McDermott said he wasn't prepared to name the starters at outside corner or nickel corner. At outside corner, it's Phillip Gaines or Vontae Davis. At nickel, it's Gaines or rookie Taron Johnson. "Yeah, that's one of the things we're looking at right now, whether it's going to be Phillip or Taron on the inside or Phillip outside. ... We've got a little bit of flexibility there so we'll just see how that comes out," he said.

Miami Dolphins: Ryan Tannehill is set at starting quarterback, but his backup is undetermined. Journeyman Brock Osweiler is one of four quarterbacks on the roster and said he welcomes the chance to compete. "I think every player in this league is very motivated to prove things on a weekly basis," Osweiler said. "This is a league that someone is always coming for your job and you're always trying to keep your job. That's what makes this league so special is because the competition is always so high. I think we're all constantly trying to prove something."

New England Patriots: In the epilogue to his Facebook series "Tom vs. Time," quarterback Tom Brady talked about ways he's grown weary of football the past few years. "The last couple years, a lot of parts about football weren't enjoyable when they should've been," Brady, 41, said. "Some of it was my approach. I think any time you're together with people for a long period of time, relationships ebb and flow. And I think people are just looking for something to write, talk about. ... They want to talk about a lot of drama. I'm sure a lot of teams have things like that. But ours is just to the 10th degree. "

New York Jets: A day after rookie Sam Darnold was named the starting quarterback, veteran Josh McCown said he was "personally bummed" he wouldn't be the starter but understands the decision. McCown, 39, will mentor Darnold, selected by the team as the No. 3 pick in the 2018 NFL Draft. "Obviously, as a competitor, you'd love to play, but I kind of understood which direction it was headed," McCown, entering his 16th season, told reporters. "I'm excited about our team and excited for the future... We're backing it 100 percent."
