Paradoxically, Jeff Wagenheim considers himself a pacifist (except when driving in traffic) but nonetheless writes about mixed martial arts, the world's most combative sport (other than driving in traffic). As a veteran of three decades in magazines and newspapers, he's a bit grayer than most who attend UFC fights, even along press row. (A fan watching an MMA media panel show recently referred to him as "that crazy hippie uncle," to which Jeff responds, "Groovy, man!") Wagenheim also has tackled pro football for SI.com, and writes about sports and the arts for The Boston Globe. When he's not on the road chasing the UFC, Jeff spends Sunday afternoons spinning Sleepy LaBeef and Boozoo Chavis records for a popular (but not pop) radio show in western Massachusetts.
