We've hit the quarter mark of the 2015 NFL season.

Some things have gone according to plan. The New England Patriots are undefeated and looking very much like the defending Super Bowl champions. The Green bay Packers are 4-0 and looking like the biggest NFC challengers to the Pats.

There has been no shortage of surprises as well. The Atlanta Falcons and Carolina Panthers are both undefeated. A Detroit Lions team that made the playoffs a year ago is the NFL's last winless club.

Week 5's slate features more than a few big games. Can the Seattle Seahawks stay hot in Cincinnati against an undefeated Bengals team? Can the reeling Dallas Cowboys upset the Pats?

For the answers to those questions and more, we turned to the NFL National Lead Writers and NFL Analysts here at Bleacher Report.

Here's how they expect Week 5 to play out.
