street fights are short because you have two unconditioned fighters that have no clue what they are doing on, as said already an alcohol fuelled binge.
I think if you tried to execute any kind of punch let alone a 'neck jab' your either going to lose your arm or your face to one of those guys.
If there was an easy option to winning a fight do you not think they would do it?
I can see your view and where your coming from but a bit of common sense surely would let you see its really not that simple or easy.
