The Indianapolis Colts’ career sacks leader has a new title: Pass rush consultant.

Robert Mathis officially joined the team’s coaching staff Monday after spending most of the offseason trying to teach Indy’s defensive linemen and linebackers some of his own moves.

Apparently, it’s already made a difference.

Coach Chuck Pagano credited Mathis with helping the Colts finish with four sacks in Sunday’s 16-13 overtime loss to Arizona. A week earlier, Indy struggled to find a pass rush against Jared Goff.

“Instead of rushing the passer himself, he’s teaching those guys,” Pagano said Monday. “You've already seen the dividends. It's great to have him around."

It can’t hurt to learn from Mathis, either.

The NFL 2013 sacks champion spent 14 seasons with the Colts, missing all of 2014 because of a suspension and an injury. He finished with 123 sacks and 54 forced fumbles, 47 coming courtesy of his trademark strip-sack.

Pagano never wanted the 36-year-old warrior to be forgotten.

So the Colts encased Mathis’ locker in Plexiglas and Pagano invited him to keep working with the team. Mathis couldn’t help himself,  and now he’s sharing the secrets of his success with a whole new generation of players on the Colts’ defense.

“I think it’s good therapy because you kind of wean yourself off the game,” Mathis told Colts.com during the spring. “It’s really helping me. I just love the atmosphere. I love the locker room aspect, the team aspect. Just being around and giving my knowledge to the younger guys, I think everyone wins.”
