FOXBORO — You wouldn’t know Patriots special-teams legend Matthew Slater had retired based on attendance at the team’s offseason workout program, which began this week.

Slater was photographed walking into the facility next to wide receiver JuJu Smith-Schuster on Monday.

So, what’s his role?

“It said advisor,” Patriots safety Jabrill Peppers said Monday. “I’m not really sure what that means. …

“I didn’t think he was done anyway. I think this is his way to stay engaged but take the load off his body and get some more time with the family but also still be a part of the organization.”

Slater retired as a three-time Super Bowl champion, eight-time All-Pro and 10-time Pro Bowl selection.

Cornerback Logan Ryan, who won two Super Bowls with the Patriots, announced his retirement on Tuesday. Ryan was a third-round pick out of Rutgers in 2013 and patrolled the secondary for years next to college teammates Devin McCourty and Duron Harmon … Peppers praised new head coach Jerod Mayo and said he was glad the team didn’t lose him this offseason. He also saved praise for former head coach Bill Belichick.”I’m thankful for Bill. That’s a guy I have a lot of admiration and respect for. … I’ll always be forever indebted to Bill. But at the end of the day, it’s a business.” Peppers said he doesn’t believe Belichick is done coaching … The veteran safety also spoke openly about the NFL’s new rule banning swivel hip-drop tackles. “I don’t like it. I don’t know how you officiate it. It’s a 15-yard penalty, is it a personal foul? So if someone does it twice, do they get eliminated from the game? I just have a lot of questions about it like what are they looking for? What draws the flag? Because it’s just going to be how it is when we hit a guy really hard and the optics of it rather than some sort of protocol that they have for when the throw the flag. We don’t know. I’m sure we’ll figure it out in preseason.”
