CHAPEL HILL — Hours before the Big Ten and Pac-12 pulled out of football this fall, North Carolina coach Mack Brown said he doesn’t envision the Atlantic Coast Conference endeavoring to play on if other power conference cohorts drop their pursuit.

“I don’t see leagues playing by themselves,” Brown said Tuesday, in a video conference with reporters. “I think if you see three or four of the leagues saying they don’t think it’s healthy, then I think that people across the country would really be concerned that if enough people think it’s not safe, then why would we do it?
