Pac-12 commissioner Larry Scott has given thought to playing some games on Sundays this fall should the NFL season not be played. "We certainly are monitoring the situation," Scott said. "We have no plans in place at this time, but you want to be prepared and consider all options. Still, these labor situations have a way of getting done the closer they get to a critical situation." Should the NFL's labor unrest push into the season, it would create a big void on the nation's TV airwaves. Fox, CBS, NBC and ESPN carry NFL games, with Fox and CBS carrying the bulk of the action.
