With all respect such comparisons are anachronistic and hopelessly futile.
A person can only thrive within the environment he exists.
While today’s players are undoubtedly more athletic, would they prosper or even survive in earlier times ?
Would they cope with the harder and more brutal ( by today’s standards) tackling ?
Would the sheer physicality of previous times negate their modern day abilities.
How would they fare in the days before substitutions , or even when only one substitute was allowed , when players had to play on carrying injuries that nowadays would warrant immediate withdrawal?
Ball excelled in the game , that is undeniable and to denigrate his standing by comparison to today’s game is not only foolish it’s deliberately disrespectful and devalues the game entirely.
