Vito was a tough cookie and had it not been for his scar tissue he would have done better in many fights. Hart was one of the hardest hitting Middleweights in that era, vicious puncher with the triple hook. Vito took his best and did the job. Intestinal fortitude as Howard Cossell used to say about him.
If we're talking Benn in his middleweight days I can see Antuofermo outlasting him. Vito is a lot more experienced than Nigel at Middleweight. There is alway's the chance of cuts but if Benn can't put him away I see Vito coming on strong from the halfway point to force a stoppage specially over 15. Benn's best chance of victory is to box.
