Go ahead and daydream, Jets fans. Let yourself in. Go ahead and go … there. To borrow from former Colts coach Jim Mora’s memorable 2001 postgame visceral rant: “What’s that? Ah … playoffs? Don’t talk about … playoffs? You kidding me? Playoffs? I just hope we can win a game. Another game.’’ There was no talk of the playoffs coming out of the Jets locker room after they battered the Bills, 34-21, Thursday night at MetLife Stadium in a game that was not nearly as close as the final score indicated. The Jets, after all, are 4-5 and just ended a three-game losing streak and are still in last place in the AFC East. But there’s more to this than the numbers. Firstly, during the Jets’ three-game losing streak they held second-half leads in all three games (two touchdown leads in two of them) and lost by seven points to the Super Bowl champion Patriots, three points to the Dolphins on the road and three points to the Super Bowl runner-up Falcons. Secondly, even the most ardent Jets detractor cannot deny that that Jets are an improving team with developing young talent that has become one of the surprises the NFL.
