PHOENIX -- Jeremy Hill remembers well the first time he saw Tyrann Mathieu go through a live practice -- and he remembers being blown away.
"He just has a different speed to him," said Hill, the Cincinnati Bengals running back who played college ball briefly with Mathieu at LSU. "He might not be the fastest guy out there, but how fast he plays the game of football, it's unreal. It's unmatched."
Mathieu's football speed will be tested by Hill's Bengals on Sunday night when they visit the Arizona Cardinals in one of the biggest games of the week.
