Other than avoidance, what would you do differently. Here are some examples of what Krav would have us do:
1) Fast and violent on the first attacker, keeping him between me and others potential adversaries;
2) Make an example of the first guy with groin kicks, elbow strikes, knees to the midsection, hammer-fists to the jaws, until he collapse to the ground;
3) Continue to assess the threats and get out quickly.
FYI, the guy who wrote the article does seem to be qualified.
