So many fighters with so many variations of jabs that are as random in style as the way you may knock on a frontdoor. Some are used by as a punch of preservation, a feeler and literal point scorer barrier. Or the hurt punch through a target shot..a power shot in and of itself that kicks in the door as a package deal with combos to follow and included...sniper jabbing like a fencer working cuts and painting a canvas. A solid stick jab to the midsection is great as a positioner. Guys like a later Camacho, Yuri Foreman, Hill, Winky, Manuel Medina or a Wlad were masters at winning full rounds with it. Guys like Quartey or return Foreman could punch your chin into the back of your neck with it. Jeff Chandler, Tapia, Finito would roll off hurting combinations. Watching a master jabber can be love or hate, all in application. The only thing that may be entertaining than a ko is watching a guy break a guy, literally minute to minute with a concise sharp accurate jab that leaves them looking silly and stunned.
