50/50
His style was boxing, but he had more than one person to deal with. In the ring, you're more focused because you can be. Something like this, you're using wide-sight, and dealing with centers of movement rather than specific points.
Backing up helped him up quite a bit, if you keep moving away from the attackers, it keeps them all in front of you. He got lucky in that they all sucked and all just kept filing in front of him.
