i think he was trying to hit with his shoulder pads and did. You can see he hit his right shoulder pad squarely on maclin, his head just hit first and unfortunately it looks bad. I think if he was intentionally trying to lead with his helmet maclin would of got struck on the side of his head and might not have been able to walk away.
