If he'd have carried on and fought up to 1959 I reckon he'd have lost to both Patterson and Liston. Not because they were better, but because Rocky would have been way on the slide by then. As Lyle said, he struggled with his back by the end and was fed up with the training.

It's a pity really because we missed out on a Liston/Marciano fight by just a coupled of years, which would have been IMO one of the best match ups in history. Prime for prime I'd still pick Liston to win due to his size advantage, but Rocky would have given it a hell of a go.
