I think his best combo was the left hook followed by the right uppercut...he finished a lot of guys off with that too.

He had KO power in each hand and he'd hit you with the kitchen sink if you gave him the chance, as Archie Moore found out, he forearmed Archie on the top of the head while beating him into submission.

And Rocky never really got hurt by anyone's punches he got knocked down plenty of times but he never wobbled or got truly hurt by a punch....his defense wasn't good at all but his awkward style and constant pressure made it hard for his opponent to catch him multiple times with full power without getting nailed in return
