Ricky Williams -Joe or Pro?

Williams became the first active player to participate in the series. Dressed in a blue-and-white uniform, Williams runs through a cone-marked lane while "Joes" try to tackle him before he reaches the end zone. One participant named Ray was steamrolled after meeting Williams head-on. A smile was visible under the running back's helmet as the "Joe" struggled to his feet and on-lookers laughed.
