What little moves & tricks have you seen recent ATG fighters take from older ATG's?

Juan Manuel and Rafael Marquez both in their stances and offense mirror Berinstein's finest creation, Ricardo "Finito" Lopez. They were never as smooth, fluid, defensively minded, or had one punch power like Finito could of summoned, but both bros became great nonetheless.

Kostya Tszyu was using the check left hook before Floyd.

SRR wasn't the only smooth operator before Ali Gene Tunney would make world class punchers look bad and get humbled. Ali did it to Liston and Foreman. Tunney did it to the powerpunching monster of his day the immortal Jack Dempsey.

But of recent times obviously Broner is closest to Floyds style and he freely does not deny it and really there's nothing wrong with it. Broner might actually become more of a crowd favorite, but time will tell how great he might become.
