Beneath Mack Brown’s incomparable charm and irresistible folksiness lies a cold-blooded, calculating politician with an ego the size of Texas, USA TODAY Sports columnist Dan Wolken writes. That’s not a criticism, but rather a compliment. You have to be incredibly talented not just as a football coach, but as a human being, to pull off what Brown has pulled off over a 40-year career. And we’re not talking about winning a national championship in 2005. At 73 years old, long past the point where his contemporaries have either quit or been pushed out of their last coaching jobs, Brown still thinks he’s the best person on Planet Earth to be the head football coach at North Carolina. He’s wrong, of course. Incredibly wrong. Embarrassingly wrong, as Saturday’s 41-21 loss to Boston College showed.
