Belichick Has Reportedly Not Signed Contract With UNC

Well clearly he hasn't done anything yet that would require official capacity. HE hasn't hired anyone... he just tells the personnel department who he wants (and perhaps a salary), they take care of the actual hire.
He’s not turning in expense reports for recruiting trips, doing it on his own dime? He’s not doing press conferences sporting UNC gear? He’s not signing recruits with the understanding that he doesn’t really work for the University? Seems like a rather wonky business model. Is he being considered an intern?
