Former Mart Panther and UT star Quan Cosby is quickly proving that he belongs in the NFL. 

He's the starting punt returner for the 4-1 Cincinnati Bengals, and for good reason. 

Cosby has 223 yards in punt returns this season (2nd best in the league), he is averaging 13.1 yards per return (7th best in the league), and his 60 yard return is the 4th longest in the NFL this season. 

Not bad for an undrafted free agent who many scouts said was too small to contribute at the next level.
