G.O.A.T.
John,Ben,
Agassi 2H BH spin averages about 1700rpm. Nadal about 2200rpm. That's a significant difference. Remember there is no such thing as a flat shot with no spin. It's a matter of degree.
Have they checked the RPMs of some past greats like Borg, Lendl, Connors and Wilander? I'd be curious about the RPMs on all of them.
