Jeremy Kerley estimates that he catches between 100-150 passes a day.

“That’s my job: catch the ball,” Kerley said this week.

He has been doing a good job of it for the Jets. Kerley has been targeted 17 times in four games this year. He has caught all 17 passes.

“He’s reliable,” offensive coordinator John Morton said. “You like that as a play caller and as a quarterback. He’s been really reliable.

He can catch. Anything that is thrown at him, he’s catching it.”

The Jets signed Kerley during Week 1 of the regular season after the 49ers cut him. The move has been a key to the Jets’ offensive success. Kerley seems to come up with big catch after big catch. Seven of his catches have come on third down, and last week he made a crucial catch to set up a long field goal before halftime.

“The key to having a great offense and having a successful, winning team is converting on third downs,” Kerley said. “You’ve got to keep your team on the field. That’s always been my thing. When it’s third down, I turn it up a notch and make sure whatever happens, we don’t stop this momentum and we keep going and put something on the board.”

Kerley said he looks for people to play catch with every day before, during and after practice. He has gotten a good rapport with quarterback Josh McCown in their short time together.

This is Kerley’s second stint with the Jets. The 2011 fifth-round draft pick is having a much better season this year than his last with the Jets in 2015. He already has surpassed his catch total (16) for that entire season. Former offensive coordinator Chan Gailey seemed to write off Kerley immediately that year, and he had no role.

“That just shows how unfortunate that situation was in 2015,” Kerley said of the comparison between that year and this year. “That was then, this is now. It’s just hilarious. I really wanted to be a part of helping that team … but that was then and this is now.”

Kerley said he is enjoying his return to the Jets after one year in San Francisco.

“It’s special to be a part of, especially when everybody thought we were going to go 0-16 or whatever,” Kerley said. “As soon as I came in this locker room, we knew what we had. We knew we were special. We’ve got a whole bunch of young guys that are just hungry. We’ve got a whole bunch of older guys who know how to play. It’s cool to be a part of it. It’s an honor.”

Patriots special teams ace Matthew Slater has a fan in Jets special teams coordinator Brant Boyer.

“That guy plays harder than anybody in this league that I’ve evaluated,” Boyer said. “I think he’s a special guy because his effort. He’s non-stop, and guys don’t play that hard in this league like him. He’s fast and he tackles. … He can be away from the play, get knocked down and he’ll jump back up, and he’ll run you down 60 yards down the fieldHe is a hard charging guy that is a special, special player.”

The Jets waived WR Jalin Marshall on Saturday. They had just activated him on Monday after he served a four-game suspension for PED use. The Jets activated CB Xavier Coleman from the practice squad to take the roster spot.
