The youth movement is alive and well in Florham Park, New Jersey.

Rookie receivers Robby Anderson, Jalin Marshall and seventh-round pick Charone Peake made the Jets’ 53-man roster — a somewhat surprising move considering their collective lack of experience. But the trio showed considerable promise in practice and during the preseason, giving the front office reason to believe in their potential.

Anderson, who went undrafted, led the Jets with 13 catches for 264 yards and three touchdowns in the preseason.

In keeping the three youngsters, the Jets chose to release veteran receivers Kenbrell Thompkins and Jeremy Ross.

A crowd at quarterback

The quarterbacks room will be crowded for the foreseeable future. As expected, injured Bryce Petty made the cut Saturday, meaning the Jets will open the season with four quarterbacks. For now, Petty will remain the third-stringer on a depth chart that includes starter Ryan Fitzpatrick, No. 2 Geno Smith and rookie Christian Hackenberg. Petty injured his right (throwing) shoulder in the Jets’ loss in Philadelphia in the preseason finale, but coach Todd Bowles said the team wouldn’t place him on injured reserve before final cuts.

Bohanan also waived

The Jets cut 20 players: fullback Tommy Bohanan; tight ends Jace Amaro, Zach Sudfeld and Wes Saxton; cornerbacks Darryl Morris, Kevin Short and Bryson Keeton; linebackers Freddie Bishop and Taiwan Jones; wide receivers Thompkins, Ross and Chand ler Worthy; safety Doug Middleton; running back Antone Smith; defensive linemen Tarow Barney and Claude Pelon, and offensive linemen Mike Liedtke and Craig Watts . . . Cornerback Dee Milliner and linebacker Trevor Reilly were waived with an injury designation, so there’s a chance they could end up on the Jets’ injured-reserve list.
