I guess it can be like a jab and then the degree of the impact starts separating one job from another.
There were a couple Larry Hoomes fights where he wins if he never throws the right hand. Some of the jabs Douglas landed on Tyson were really impactful.
Some of Ali's were nothing more than 'distance makers' for something else.
Some jabs set things up and some jabs sting, and some jabs actually hurt and some jabs are just there to keep someone away.
Charlie's jabs were the hurting kind.
