There's no bigger UNC football fan than me I promise you, but I'd be very wary of using a 1st round pick on Mitch. I think he has it in him to be great, but he's still unproven like Enfuego said. He did play poorly his last 3 games. That was partly due to a banged up OL and losing our field-stretching WR (Mack Hollins). I also think the hype got in his head and he pressed. That being said, the NFL is the big-boy league and he has to handle adversity/pressure in order to make it.
He could have really used another year as a college starter but most of his weapons graduated, and it's going to be a rough year in '17 for my Heels. I don't think his stock would have improved had he returned with a weak/young supporting cast, so from a business perspective he made the right call. I hope he does great.
