Jets coach Rex Ryan has likened his showdown with New England's Bill Belichick to a couple of time-tested boxers getting ugly in the ring. "From a competitive standpoint, that's like facing the world champ," Ryan said of Sunday's game between the Jets and Patriots. "You know the only way to beat him is you've got to be at your very best, then we'll see. You want to compete against the very best. Certainly, with him, he is the best coach out there -- may go down as the best coach in the history of the game -- but I'm going to take my swing at him."
