Robert Mathis has retired after 14 years in the NFL. He led the league with a whopping 19.5 sacks in 2013, leading the league, and 8 forced fumbles. He has 128.5 sacks in his career(including the postseason), 18th ever. Mathis played every one of his 210 games with the Colts and has had a win 143 times. He has been to the Super Bowl twice and won once. He has a .680 winning percentage. Robert Mathis also leads the league in career strip-sacks and has much praise from great quarterbacks. Bill Belichick, one of the best coaches ever, called him one of the most destructive players in the league. With Mathis gone, and lots of controversy over the head coach and general manager, the Colts will return a different team next year.
