Several former Champs KO'ed 16 in a row including Rocky Marciano, Al Hostak, Jimmy Wilde, John L. Sullivan, Jeff Lampkin and Ike Quartey just to name a few.
Yes it was Al Hostak...Hostak was a superior version of Kelly Pavlik who's middleweight champ today...Hostak once kod the great Freddie Steele, himself a great fighter...Hostak had bad hands, otherwise he woulkd have been even more successful...Great puncher was he though...
