He's not going to win with recruiting. It's UNC and the ACC and they're already a mid team in conference. Coaching college kids now will be vastly different from when he did it 40 years ago. All he is is an NFL name.
They will have a good defense that's for sure, but UNC won't be bringing in top 10 classes and if you can't get those recruits, you won't win. UNC doesn't have the money Georgia, Texas, Bama, UF, Miami, Clemson, FSU, LSU, Tennessee, OSU, Penn St, ND, Michigan, Ole Miss does....that's 14 teams vying for the same top recruits.
NIL CFB is a different animal these days and cruitin is a 24/7/365 job for the entire staff including the Head Coach. This won't end well for BB. He's still a legend NFL coach, and will be great defensively.
