FOXBOROUGH, Mass. — Newcomer Danny Shelton, the 335-pound addition to the Patriots’ defensive line this offseason, says he is well versed in the work from former nose tackle Vince Wilfork.

“Growing up being a fan of him and being here now, we always see film of him running the defense a certain way and running a play a certain way,” Shelton said as the Patriots continued their voluntary offseason workout program at Gillette Stadium. “It’s pretty cool to see that and be in this environment.”

A first-round pick of the Patriots in the 2004 NFL draft, Wilfork stuck around for 11 seasons, earning five Pro Bowl berths and contributing to two Super Bowl championships.

As for Shelton, how long his stay in New England will be is very much in question after the team declined to pick up the fifth-year option on the rookie deal – at a cost in excess of $7 million – he signed as a first-round choice of the Brown in 2015.

“Obviously it (stunk) at first, but at the same time you’ve got to think of it as an opportunity,” said Shelton. “For me, I’m just grateful for the opportunity to be here for the year and to just be able to try my best to dominate and to put myself out there, and see what happens after that.”

More disappointing than dominant during his time in Cleveland, three years after making him the 12th overall selection out of the University of Washington, the Browns were willing to make the mid-March trade that sent Shelton and a fifth-round pick in this year’s draft to New England in exchange for a third-round choice in 2019.

In three seasons in Cleveland, Shelton appeared in 46 games, starting 45, totaling 128 tackles and 11/2 sacks. After ranking 20th in the league, allowing 114.8 yards and 4.7 per carry in 2017, the Patriots thought adding Shelton’s wide body to eat up space and stuff the run in their defensive line was worth it.

“Really, it’s just a matter of stopping the run first and having the opportunity to rush the passer,” Shelton said of the role he envisions for himself with his new team.

The playbook isn’t all that’s new to Shelton since he’s moved from Cleveland to New England; so, too, is the rigorous conditioning that is so much a part of the Patriots’ way.

While saying it’s “going great” and “I feel like my body has adjusted now to all the running,” Shelton added, “it’s pretty crazy but I like it.”

Shelton said he believes there’s a method to the madness.

“What I like about the change is that I know that my body will be more trained for that endurance and trained for the fourth quarter, overtime,” he said. “I’m excited for the rest of the year.”

ROBERT KRAFT, owner of the New England Patriots, was deposed Friday in connection to Colin Kaepernick’s collusion case against the NFL, according to multiple media reports.

Kraft joins Broncos part-owner John Elway, who answered questions earlier in the week, and Houston Texans owner Bob McNair among those questioned.

Kaepernick filed a grievance against the league claiming collusion back in October, and remains unsigned by any team. The grievance claims the league is blackballing him for kneeling in protest during the national anthem while playing for the San Francisco 49ers.
