Correct. They would. I'd favour the 20s fighters against many of their counterparts today .. Jack Dempsey. Benny Leonard. Gene Tunney. Tommy...
I don't think it's evolved to the point where somebody like Canelo would beat Jack Dempsey.. same way i dont think i.e Crawford beats Tunney.....
Bit of a leftfield choice but I'm saying Tunney.. a skilful scientific fighter ahead of his time.. either him or Ezzard Charles for me..
