Billy Martin is quoted as saying that no one possessed the shear power of Mickey Mantle. The Mick is on record of hitting some of the longest homeruns of all time. Modern players such as Judge and Stanton could have more power as measured by the velocity their home runs. Does the Mick's power measure up to that of the modern era players?
I'd love to hear from Zappa about what his Dad thought of Mick's Power.
Modern lawnmowers certainly have more shear power than vintage models. Is that what we are discussing? Or sheer ? And what does that even mean sheer? Is that a particular type of power ? Yeah OK Billy Martin is the definitive voice on the subject.
As in other sports, players today are better conditioned, stronger, etc and hit harder. And pitches are much faster too, which increases force (velo) of the hit. So while Kong remains my favorite all time player, I won't try to argue he hit the hardest, farthest, etc. Mantle either. You've got to look at the top guys in this century.
