During Super Bowl week, Christian Okoye–the retired bruising Chiefs running back known as the “Nigerian Nightmare”–joined For the Win on Radio Row to play Tecmo Super Bowl, pretty much the greatest sports video game ever conceived, and one in which Okoye is an absolute monster.

Okoye was making the rounds on behalf of the P.A.S.T. Retired Athletes Medical Resource Group to promote “The United States of Football,” a film about football injuries and their repercussions. The film features Mike Ditka, Ricky Williams, and Jim Brown, and can be downloaded through the group’s website.

In the Tecmo arena, Okoye wasn’t great. Despite his virtual character’s legendary status, the Nightmare went three-and-out. He may have been able to run through real NFL players for 1,480 yards in 1989, but in Tecmo Bowl, he needs to try the zig-zag.
