Top Stories Tyrann Mathieu emerged as more than just a feel good story in 2015.He became a Pro Bowler, a Defensive Player of the Year candidate and a team leader.So, when his season was cut short in Week 15 to a torn ACL, the team’s mood understandably changed.“It’s hard to say what he means because it’s one thing to say how good of a player he is on the field, but the inspirational that he is off the field, the amount of love that the guys have for this guy in the locker room,” Cardinals GM Steve Keim mused on the Big Red Rage on Arizona Sports 98.7 FM Thursday. “I can tell you that when we went into the locker room after we won the NFC West against the Philadelphia Eagles, and everybody’s putting on hats and t-shirts, it was a somber locker room.

That shows the deal of respect that they have for him.”In 14 games, Mathieu collected 89 total tackles, 11 tackles for loss, a team-leading five interceptions, one sack, one forced fumble, three quarterback pressures and one quarterback hit.He was anywhere and everywhere on the field, making his presence felt while making plays.On a defense filled with stars and personalities, he shined the brightest.The 23-year-old has come a long way since being kicked off of the LSU football team due to off the field transgressions, and his growth as both a player and a person has often led to him being described by head coach Bruce Arians as his favorite draft pick of all time.That sentiment is one Keim does not necessarily disagree with, though he said he does not have a favorite player.“But I can tell you there’s not a player that I’m more proud of than Tyrann Mathieu,” he said.Now, the trick will be keeping Mathieu — who is rehabbing from his second torn ACL in three seasons — in Arizona for the long haul.
