You mean the same physical strength and CoA with which he hot washed by Base King in close combat, the same Base King that crashed into a building vs Marco ?
Yeah Marco surely can't handle Zoro's physical strength and CoA.
As said before. It does not make any difference if Zoro beheads Marco with Asura or a no named slash, he regenerates that's the point. King doesn't have that. Once his gimmick is exposed all Zoro needs is one good slash too put him to the canvas.
Marco definitely beats Rooftop Zoro.
