I'm adding this base card today for my 2013 Topps Chrome set. I pulled a Blue Wave refractor out of my box I broke but no base rookie. Mathieu had a great 2011 season in college and after sitting out 2012 with an injury made a huge impact once he reached the NFL. His card values aren't anywhere near what offensive rookies are getting but he does have a strong following. According to ESPN.com:
Mathieu showed in 2013 what he could do after a year away from football. He was a finalist for Defensive Rookie of the Year. The Honey Badger persona followed him to the NFL and he embraced it on the field.
He was versatile in his rookie season, playing free safety and cornerback in addition to special teams in 13 games before his injury. He was the Cards’ fifth-leading tackler (with 63), and if he had finished the season, Mathieu could have been in the top three. He added two interceptions and a sack to his rookie stat line.
