There have never been alot of one shot KO punchers. One guy who can take a guy out with one shot right now is Nonito Donaire.
To be fair that is true. I don't think he hit Barrett with a flush shot once and put him on his arse 5 times
Miranda Wlad Darchynian People say Manny but who does he ever 1 shot KO I can only think of 1 guy and that is Hatton the rest are TKO's or breakdown swarming fights that ware people down
There weren't any more one punch KO artists in the good old days as there are now, at least on a relative scale. There are plenty of them out there.
Briggs is sort of a one shot guy. I'll leave how effective he is at this stage up for debate, but he does seem to go for the one punch KO. I think I read him quoted somewhere saying that's what he wants to do is hit the quick one shot counter.
