Detroit responded to Suh's departure by trading for defensive lineman Haloti Ngata.
Mathis spent the first 10 seasons of his career with the Jacksonville Jaguars before joining the Lions.
"Familiarity is key. That's never a minus," Mathis said.
"I'm very confident in the guys who we have," Mathis said on a conference call Thursday. "I'm also confident in our personnel department and getting people here to help us. That's what the NFL is all about. You've always got to lose someone."
"Having someone plug in that gap — that's always the key," Mathis said. "In any business field,Wholesale World Cup Jerseys, regardless of whether it's sports or not, if you lose a big, key piece of what made you successful, having someone step up and plug in that gap, that will be the only way that you're able to be as successful as you were before."

ALLEN PARK, Mich. (AP) — Rashean Mathis is returning to a Detroit defense missing its biggest star from last season.
The 34-year-old Mathis has been a steady part of Detroit's secondary since the Lions signed him two years ago. He had 42 tackles and nine assists last season, as well as an interception he returned 41 yards for a touchdown in an October loss to Buffalo.
He still has high hopes for the Lions in the post-Ndamukong Suh era.
