Here are the most interesting stories Sunday in the AFC East:
The Buffalo Bills can make a statement by upsetting the New England Patriots.
Morning take: The Bills believe they have closed the gap, and we're about to find out by how much. This is a big swing game with plenty of AFC East implications.
How serious is the hip injury to Patriots Pro Bowl guard Logan Mankins?
Morning take: Mankins is as tough as they come. He played last year with a torn ACL, which is almost unheard of. But this hip injury will keep him out today against the Bills. So it must be a pretty bad injury.
Can the New York Jets' defense stop San Francisco 49ers quarterback Alex Smith?
Morning take: Smith has been vastly improved since Jim Harbaugh took over the 49ers in 2011. Smith has reduced his turnovers and that's what New York’s defense thrives on. If the Jets can't stop the run, it will be an easy day for Smith.
Can Miami Dolphins rookie quarterback Ryan Tannehill handle an aggressive Arizona Cardinals defense?
Morning take: I doubt it. This is an Arizona defense that baffled Tom Brady for three quarters on the road. Tannehill is a rookie and the Cardinals are at home. Miami's running game is key.
