Lest anybody get the wrong idea, I'm not suggesting that fighting multiple attackers is preferred, or likely to be wonderfully successful.
I'm just saying that certain concepts are probably going to be crucial. Not allowing simultaneous, multiple openings to multiple people is right at the top of those concepts.
Some of the things I mentioned earlier were focused on more open space. If there is cover, or potential obstacles one can put between oneself and the gang, those should certainly be exploited, if one must fight.
As always, detecting and avoiding the problem in the first place is best. It's just that we can't always manage that.
By the way, Willie Lowman, who were you referring to as "Captain America?"
