If Boyer plays at the very top of his game ( like he did at state and in his one match with Mccoy) he has the potential to beat anyone on that day. He has a much bigger game than Mccoy. Problem is consistency, fitness and court coverage can be much better, but he has been working at these things. If he has a normal or worse day he could lose 6-2 6-2, or if he is playing his best he can win it.
