The nominations for Broyles come mostly from the 65 P5 programs each with an OC and DC, that's 130 positions. There's a handful of non-P5 nominees each year, but basically there's 40-45 P5 nominees only requiring a peer to nominate you. The other 10 or so nominees come from other FBS programs.
MoBS only had to goad some peer coach to nominate him and he probably worked all year on it. There isn't any committee that selects assistants. Of the 55 or so nominees, the first cut gets it to 15, then a second cut to 5 finalists. If you're on either list (15 or 5), you've probably had a great season. Doubt any of MoBS's nominations made it past the circular file.
Maybe he's relegated to cheerleading, ball spotting, pictures on those idiotic signs, dance routines, slamming his oversized torso into an undersized jersey, and misc BS like that. If he recruits, game plans or calls plays during the game unc is screwed. I think they're screwed anyway because that guy is grossly incompetent, but that's their problem not ours.
