24. Christian Okoye, RB, 1987-1992: Okoye came to the United States as a discus thrower but wound up falling in love with the game of football at Azusa Pacific University. Okoye used to lap the field before games in order to intimidate opposing teams with his 6-foot-1, 253-pound physique. He wore massive shoulder pads, also as a means of intimidation. The Nigerian Nightmare was one of the most difficult players to tackle in football, and if the Chiefs got to the final minutes of the game with a lead and the ball, there was little you could do to stop Okoye from running out the clock. With 4,897 career rushing yards, Okoye ranks fourth in franchise history. (Photo by Jonathan Daniel / Getty Images)
