A year ago this weekend, Davis Webb was blindsided.

“You never see it coming,” the quarterback said on his first day as a Jet last September, two days after the Giants pulled a stunner and cut him.

If it happens again this year — and it is increasingly looking like it might — Webb may be better prepared for what’s to come when the Jets slim down to a 53-man roster after Thursday’s preseason finale.

“Been here before,” the 24-year-old said Tuesday after practice. “Was in a similar situation a year ago, I guess. This is my, I think, fifth head coach, fifth GM total. So nothing really fazes me. Just trying to go out there and do [my] best and be a great teammate. That’s always the No. 1 goal, just be a good teammate and work hard.”

Webb had been taking reps as the Jets’ third quarterback early in training camp, but Luke Falk got into Saturday’s preseason game against the Saints ahead of him. It may have been a sign as to which way the Jets are leaning for the No. 3 quarterback battle, if they even decide to keep a third one behind Sam Darnold and Trevor Siemian.

Head coach Adam Gase said Thursday’s game against the Eagles will be a big one for Webb, who is expected to get more playing time than he has in the first three. Even if he is not in the Jets’ plans, he has a chance to catch the eye of one of the other 31 teams in the league.

“This is the NFL. Every day feels like that,” said Webb, who could also be a practice-squad candidate if he gets cut and goes through waivers unclaimed. “There’s plenty of people that know other people in this league. [If] Coach knows a coach in Indy or Detroit, people talk. At the end of the day, everybody watches the tape. Depends how you play in these preseason games, and Thursday’s just another one of them. It’s the last one, you want to play your best one and that’s the goal.”

So far in the preseason, Webb has completed 11 of 22 passes for 77 yards and two interceptions. Both interceptions came against the Giants, the team that drafted him in the third round in 2017 before dumping him and keeping Alex Tanney and Kyle Lauletta as Eli Manning’s backups.

Once thought of as Manning’s heir apparent, Webb has still never played in a regular-season NFL game and spent the last month trying to find consistency on the field after learning another new offense.

“Some of the days in practice have been good,” Gase said. “He’s had a couple rough days as far as the game play goes. He’s had some decisions that were really good that just the result wasn’t exactly what he wanted or what you’re looking for. But the decision-making process of it was right. It’s one of those things where you just need other guys to do their job sometimes. It’s just when you’re the quarterback, all that gets deflected to you.”

It doesn’t help Webb that he isn’t Gase’s or new general manager Joe Douglas’ guy, as it was former GM Mike Maccagnan who originally signed him to the Jets’ practice squad last year. He wasn’t Pat Shurmur or Dave Gettleman’s guy, either — Ben McAdoo and Jerry Reese drafted him — and he saw how that worked out.

Falk, meanwhile, spent last fall with Gase on the Dolphins and is 16-for-18 for 139 yards and two touchdowns this preseason.

“Coach Gase is a great play-caller,” Webb said. “My job is to just get us into the end zone, make the right play, make the play-caller right, and I haven’t done a good enough job of that so far. I’ve done some really good things, especially in practice, and some plays during the game. Hopefully it’ll all come together in the last one.”
