WHITE SULPHUR SPRINGS, W.Va. — Jaxson Dart snapped out of his early training camp funk on Thursday with his best practice under John Harbaugh to date.

The Giants’ second-year quarterback completed 16 of 19 passes, including a stretch of 12 straight completions that spanned three different periods of play.

“He made some good throws,” Harbaugh said of Dart. “He got us in some good plays. All three quarterbacks got us into some good plays versus pressure, which is good to see.”

Tight end Isaiah Likely continued to be Dart’s favorite target.

The QB hit Likely for four receptions. He threw to him in all five periods the first-team offense operated. And his best completion, on his first series, was a fade to Likely down the right sideline over top of Deonte Banks.

The offense couldn’t run the ball, and Dart was sacked three times early by defensive tackles Darius Alexander and Josh Tupou and safety Tyler Nubin.

But Dart mostly got the ball out quickly against the blitz on a day when defensive coordinator Dennard Wilson was sending a lot more pressure, and he finished the practice by completing 7-of-8 passes on a final drive capped by a touchdown pass to Darius Slayton in the red zone.

Darnell Mooney, Calvin Austin, Theo Johnson (twice), Devin Singletary and Dante Miller also hauled in passes.

“They did some good things,” Harbaugh said. “That long drive we did there at the end, they executed a lot of plays there. One thing you learn in those kinds of periods is you get frustrated with a play you don’t make, but on offense you get two more chances. You still have an opportunity. if you make a play, you keep a drive alive, you can break out.”

Backup quarterback Jameis Winston also sizzled, completing 19-of-20 passes while running the second-team offense, marking his second straight explosive padded practice including Tuesday’s six-touchdown red zone performance.

“It got better at the end,” rookie right guard Francis Mauigoa said. “We need to focus on starting off hot. Man, we just need to pick it up from the jump. I mean, we’re earning our days. We’re out there grinding, and we’re learning our play calls as we go, but we got to start off quick.”

NABERS LOOKING STRONGER

Malik Nabers looked very good Thursday running routes during individual drills, cutting off his right leg and leaping to catch a couple footballs and looking strong while doing it.

Harbaugh said Nabers “will be working his way back into practice more and more as we go here. We’ll see what he’s ready to do each day.” So he could be participating in team drills soon, which creates an encouraging outlook for his early season availability.

Harbaugh credited Allison Boudreau, the Giants’ coordinator of rehabilitation and return to play, for bringing Nabers along at the appropriate pace.

“I feel like Ali, who is our coordinator for return to play in the training room, she’s working with him on situations where you’re off balance, landing off balance and unpredictable situations you’re gonna get,” Harbaugh said. “Rather than just doing the normal rehab and then going out there and all of a sudden being surprised by the awkwardness of football, try to create that as much as you can in a controlled setting. I think she’s doing a great job with that, and Malik’s working really hard at it.”

Elsewhere on the practice field, safety Jason Pinnock replaced Nubin mostly on the first team. Nubin played some reps with the ones but mostly logged time with the backups … Slayton logged a couple reps with the third stringers at one point, which was unusual, although he made the final TD catch from Dart … Third-string linebacker Zaire Barnes had a pick-six of quarterback Brandon Allen … The Giants will hold their final West Virginia practice Saturday before returning to New Jersey to prepare for next week’s preseason opener against the Minnesota Vikings.
