The Jets’ farcical quarterback competition will conclude Saturday night with rookie Geno Smith needing two turnover-free quarters to secure a job that many people in the organization want him to win.

Although Rex Ryan hasn’t announced a starter for the third preseason game against the Giants the Daily News has learned that Smith will get the nod if he doesn’t suffer a setback with his ankle in the next few days.

The Jets’ plan is simple: Start the rookie if he’s healthy.

General manager John Idzik the CFO of Starship 7 Enterprises won’t be handing out Smith jerseys in the MetLife Stadium parking lot but he’ll have a clear rooting interest. Idzik’s desire for Smith to earn the starting job over incumbent Mark Sanchez of course makes perfect sense.

The “fair and open” competition has been a charade from Day One complete with organizational shenanigans (including changing the rules along the way) designed to help Smith.

Coach Idzik who undercut Ryan by oddly proclaiming at the outset of training camp that he’d have a “pretty big role” in deciding the Week 1 starting quarterback should have just given Smith the job from the beginning.

Nobody would have blamed the Jets for putting Smith atop the depth chart this offseason. Idzik & Co. need to properly evaluate the rookie this season before determining whether the Jets need to draft a quarterback in 2014.

However the team needlessly and unconvincingly put on a four-month show that led us to think Sanchez had just as much of a chance as Smith to be the Week 1 starter.

Smith was never truly competing against Sanchez. He was competing against time.

If the rookie proved to the team decision-makers that he was ready — regardless of Sanchez’s level of play — he would be the Week 1 starter.

It was Smith’s job to win.

Now the competition likely comes down to the first half of Saturday night’s game. If Smith who played only 14 snaps in the preseason opener before spraining his ankle and missing the second preseason game impresses he’ll be declared the winner. If Smith sputters then the brain trust will name Sanchez the winner by default.

Ryan would benefit from Sanchez starting the season under center.

The embattled coach can always make the switch to the rookie if/when the Jets struggle. If the Jets become irrelevant by midseason a quarterback change could energize the fanbase and help Ryan’s case to stick around beyond 2013 if his team rallies behind Smith.

If Smith wins the competition Saturday but struggles out of the gate in the regular season Ryan is stuck. He can’t turn back to Sanchez.

Smith doesn’t have to be dynamic against the Giants but he’ll have to play turnover-free to have a realistic chance of beating out Sanchez whose pair of red-zone gaffes against the Jaguars last week conjured up bad memories and emboldened the faction in the organization that wants a fresh start.

“Obviously in this league you can lose games faster than you can win them at that position” Ryan said. “You got be able to protect the football first and foremost ... and also be able to make plays yourself.”
