How much can Giants expect from Adoree’ Jackson vs. Vikings?

Jackson uncertain how many snaps he will be able to play in Week 1

Although it took until roughly a week before the beginning of the regular season, cornerback Adoree’ Jackson said Monday “I never thought the door was closed” to return the New York Giants.

“No animosity, no feelings, no ill intentions on, I think, on my end,” Jackson said. “And then when I came in and saw everybody, it was like being at a family reunion.”

Now that he is back, signing jut days before the regular-season opener against the Minnesota Vikings, how much can the 28-year-old legitimately expect to play on Sunday?

Jackson admitted he “might be gassed” if he tried to play a full game.

“I wouldn’t put a number of snaps how I can play right now,” he said. “We’re going to see this week, getting ramped up and working on my condition and seeing what I need.”

Jackson said he has always focused on being prepared to play Week 1.

“I know football shape is going to be a lot different from what I’ve been doing,” Jackson said. “But I always kept my mind set, focused on being ready to go Week 1.”

Daboll wasn’t certain how much Jackson would be able to play Sunday against the Minnesota Vikings.

Head coach Brian Daboll admitted Monday he wasn’t certain what to expect from Jackson right away.

“We’ve got to get him out here and ramp him up and see where he’s at,” Daboll said. “We’ll take it day by day, see where he’s at and how much to play him, how much not to play him.

“By the end of the week, we’ll determine what we’re going to do relative to roster, play time, all those type of things,” Daboll said. “You try to make it as competitive as you can make it. And we’ll play the guys we think give us the best chance.”

Jackson said having been coached previously by Giants defensive coordinator Shane Bowen will help him make up for lost time.

“Being able to know Shane and some of the things that he did when I was in Tennessee with him, understanding some of the verbiage may have changed, but easy for me to wire my mind onto how to compartmentalize what these defenses may be and some of the calls, so I think that’s helpful,” Jackson said.

Cor’Dale Flott and Nick McCloud had been competing for the starting cornerback opposite Tae Banks that had been Jackson’s last season. In the end, the Giants decided to go back to Jackson.

“Like we’ve always said, we’ll try to improve the team any way we can,” Daboll said. “Obviously, we’ve had a relationship with Adoree’. Shane has had a relationship with Adoree’.

“He looked good in the workout and got something done. So, happy to have him aboard.”

Jackson admitted that “I didn’t play to my best” last season.

Daboll did say Jackson could “potentially” return punts if Gunner Olszewski (ankle) is not healthy enough.

“Whatever may be needed,” Jackson said. “Any way to help this team.”

Jackson will not wear the No. 22 he had his first three seasons, with rookie Dru Phillips now in that jersey.

“Actually, it’s funny. Dru had asked me, did I want it back?,” Jackson said. “And I’m like, nah, you can keep it. I saw him making some plays in it. So I’m like, you got it. You look good in it.”

Roster move

The Giants announced a roster move on Monday, signing veteran FB/TE Jakob Johnson to the practice squad and released wide receiver Miles Boykin.
