Jamal Duff

Duff was born in Columbus, Ohio, but as a child, moved west with his family to Tustin, California, where he played football for Foothill High School.

However, Jamal played his college football at San Diego State University, carrying a major in graphic design.

Duff became a fan favorite as one of the Xtreme's top defensive players (recording 18 tackles and four sacks), but also for his nickname.

Thanks to an XFL rule that allowed players to put anything they wanted on the backs of their jerseys (within reason), Duff decided to name himself after an underground black comic strip character: Death Blow.

He has appeared in S.W.A.T., The Rundown, The Eliminator, Dodgeball: A True Underdog Story, Revenge, Two and a Half Men, The Game Plan, Brooklyn Nine-Nine, Torque, and Better Call Saul.
