The stench of the 2012 Jets season has lingered like a pile of dirty laundry and garbage around the organization for eight months.

Now the new season is here.

The Jets have a lot of new faces starting with rookie quarterback Geno Smith who will make his first official NFL start Sunday against the Buccaneers. Smith saw limited time in the preseason and was handed the starting job by default after Mark Sanchez was sidelined with a shoulder injury.

The Jets could have five new starters on offense Sunday and seven on defense depending on the formations they come out in.

One face that has not changed is head coach Rex Ryan who looks and sounds nothing like the coach Jets fans fell in love with in 2009 and ’10. But he’s back — perhaps for one last run. The expectations for the Jets are as low as they’ve been under Ryan.

The players and coaches know they could flip those expectations with a win Sunday.

“ I honestly believe this is a game we must win” guard Willie Colon told The Post. “We have to get off on the right foot. The sense of urgency has to be right now.”

Tampa Bay should provide a good test for the Jets. They had the ninth best offense last season and are loaded with playmakers. Their defense should be improved with the additions of cornerback Darrelle Revis (remember him?) and safety Dashon Goldson.

The Jets enter this game with a chip on their shoulders sick of hearing predictions that they will be bottom feeders. Some outlets ranked them as the worst team in football this week.
