At the risk of sounding retarded(-er) I will offer my criterion of "suitability for multiple attackers"
1) when performing whatever manuver, can you quickly disengage and run away if more people show up?
2) can you see around you?
3) When someone inevitably grabs you and tries to hold you down/knock you down so his friend can hit you, can you get control of the clinch/whatever long enough to get a dominant position and disengage?
4) can you keep people from surronding you, and force your way through the gaps?
Anybody who says they can "fight" multiple opponents is pretty silly, unless we're talking about deploying weapons and using them. People who say they've got some good ideas for being able to "escape" multiple opponents is much less silly.
