Bill O'Brien met up with his former boss, Bill Belichick, as the Boston College coach had an eventful ACC media day.

In December 2024, UNC hired 8-time Super Bowl Champion Bill Belichick to be their next head coach. Belichick started his coaching career with the then-Baltimore Colts in 1975, coaching in the NFL until January 2024 with the New England Patriots.

But Belichick, widely regarded as one of the greatest—if not the greatest—NFL coaches of all time, is already noticing differences between players at the college and pro level. And it goes beyond the obvious age and skill differences that one would assume exist between the levels of football.

Boston College coach Bill O'Brien spent time with UNC's Bill Belichick in the NFL. Here's what O'Brien said about Belichick's move to college.

The Atlantic Coast Conference has three former NFL head coaches leading its football programs this fall for the most of any league.

"It's a pro program," Belichick said. "Practice, training, food, schemes, terminology, it's all a pro program. Not to the extent that we did it in the NFL — there will be fewer plays, fewer adjustments — but it will be along those lines."

With a little more than a month to go until Bill Belichick kicks off his first season as a college football head coach, the University of North Carolina’s home stadium is set to be at capacity whenever he is on the sideline. The Tar Heels football team announced on Wednesday that all season and single game tickets for its home games are sold out.
