When Brant Boyer stepped into his room for the first time this year, he came with a message.

“There is no steps back,” he told the Jets’ special-teamers, despite the obvious factors indicating otherwise.

Andre Roberts, a First-Team All-Pro returning kicks and punts last season with the Jets, will now face them twice next year with the Bills. Roberts led the league in yards per punt return and in total kick return yardage. Likewise, the Jets average starting drive position last year was their own 29-yard line — seventh-best in the league despite a defense that was 25th in yardage.

Replacing that production is easier said than done.

“It’s challenging to replace every position,” Boyer, the Jets’ special teams coordinator, said Thursday. “Andre did a hell of a job for us, there is no doubt. That’s gonna be a challenging deal when we go to play [Roberts] twice this year, which makes it harder. But he did a fantastic job, and every position is a challenge that you have to replace.”

As of now, Boyer is uncommitted to naming a replacement. Trenton Cannon, the presumed leader, is doing a good job, he said, but focusing more on kick returns than punts. Whether he gets the returning job or not, he’ll be a core part of the special-teams unit, as he was last year. Boyer holds him up as an example of a rookie who “found his niche” — what a sixth-round pick needs to do to stick.

Despite the turnover, Roberts the most notable example, Boyer noted Brandon Copeland, Rontez Miles, Neville Hewitt and Cannon are all back.

Still, Boyer returned this year with a new boss and the biggest piece that built his success gone, and shortly followed by Jason Myers, who made 33 of 36 field goals.

“I’ll tell you, it’s part of the business,” Boyer said. “It’s a tough situation. Those guys were awesome for us. … You gain players every year, you lose players every year. And, is it hard to replace guys like that? It sure is. I’m confident that somebody will emerge and we can get that done.”

Boyer is a holdover from Todd Bowles’ staff, and the former coach valued special teams — an arrangement Boyer was content with. Whether new coach Adam Gase will do so in the same way remains to be seen.

“I think that the relationship with Adam’s been awesome,” Boyer said. “He cares about special teams, wants a real good special teams and hopefully we can give him that. I’m really excited to work with Joe [Douglas] but I didn’t know Adam before, at all. But it’s been a really good working relationship so far.

“I’m excited to see where this takes us.”
