I don't think 1-4, or 2-3 over the next 5 games is "unrealistic", I think those finishes are very realistic and the most likely based on what we have seen so far this season. Expecting anything more than 2 wins down the stretch is getting into the hope category. It's also likely they don't just win the two "obvious" game" against the Steelers and Jets, because the NFL does not usually work that way. They likely beat one of the "good" teams, and lose to one of the lesser teams.
