Going to a new team can be hard for an NFL player, but Jets linebacker Quincy Williams had a built-in guide to his new team and a place to stay because of his brother, Quinnen, a Jets defensive lineman.

When the Jets claimed Quincy on Sept. 1 off waivers from the Jaguars, they reunited the Williams brothers, who had not played together since high school.

“I talk to my brother every day and now I get to for right now stay with him,” Quincy said. “It’s like we’re younger kids again, same thing, talking football. It takes me back to my high school days when we played with each other.”

While Quinnen was the No. 3-overall pick of the Jets in 2019, his older brother Quincy was not taken until the third round that year by Jacksonville. After two years with the Jaguars, some as a starter, he was cut by new coach Urban Meyer at the end of training camp. The Jets needed help at linebacker after losing starter Jarrad Davis in the preseason.

Quincy, 25, got a crash course in the defense from the coaches, and he was able to start in Week 2 against New England. In two weeks as a starter he has 11 tackles, three for loss and has shown he can be a big hitter. He forced a fumble last week in Denver.

“I think it’s more like an adrenaline rush for me,” Williams said of his big hits. “We say get the ball out but I take it a little different way. I don’t punch at the ball. I’m more punching at the person. That’s my biggest thing. I try to get them with my speed and try to run through the player.”

This week, the Jets will need Williams to be a big hitter on Titans star running back Derrick Henry, against whom Williams played twice a year while with the Jaguars.

“The main thing is run through him,” Williams said. “When I’m tackling a person, I’m looking through him. I’m not worrying about breaking down. My coaches tell me to shoot my shot. I have 10 other players coming so my main mindset is run straight through them.”

Williams has impressed the Jets coaches.

“First of all, his speed, his explosiveness, they jump off the tape,” defensive coordinator Jeff Ulbrich said. “He’s a guy that just has different speed, different quickness, different explosiveness, very unique in that way.”

The Jets activated safeties Ashtyn Davis and Sharrod Neasman off injured reserve Saturday, and both could play Sunday in place of the injured Marcus Maye. … RB Josh Adams was waived and OL Isaiah Williams was elevated from the practice squad.
