They need Cincy to win that game against the Steelers. It's simply put they have to run the table. I don't see another scenario where they get into the playoffs.
They definitely have to run the table to get in but even that doesn't assure them a spot. They definitely need Cincy to win that game against the Steelers and probably the Cowboys to beat the Steelers next week because I don't see the Browns beating Pitt again in week 17.
Jets just have to win their games though. Anything less than 3-0 and they don't have a chance.
