He tried to lunge at Joe dont be mad because Joe has faster hands
All that can be seen is the man starting to lean forward and schilling immediately uncorked a two punch combo. He didn't raise his hands aggressively nor put his hands on schilling all he did was lean forward. As a kickboxer schilling shouldn't feel threatened by a drunk leaning forward sticking his chin in the air with his hands down.
Here is a list of things schilling could have done instead of going ballistic :-
1. Raise his palms out in a sorry expression and say some conciliatory things and move away from him
2. Put his hand on his shoulder as a friendly gesture and to monitor any incoming punch and any nice things to defuse the situation and walk away
3. Warn him off and move away while keeping eyes on him
4. Say he doesn't want any trouble and call for the bouncers
5. Use the long guard and stiff arm push him away
6. Put him into a Thai clinch and bring his head horizontal which will cause the typical untrained drunk to become helpless
7. Clinch or wrap him up and sweep him onto the floor and take him down
8. Teep him To keep him away
9. Be ready to slip any punches
10. Be Ready to block any punches
11. Be ready to parry any punches
12. Grab his hands and just physically overpower him to restrain him given that he appeared twice as strong as the drunk.anyway
