I've always thought in some cases the GOAT and the Best could be separate. For example: Jose Aldo is by far the most accomplished Featherweight of All-Time, however he is clearly not the Best FW of all time as he lost to Conor, Holloway 2xs, and Volkanovski. The "Best" FW of all time is probably Conor or Volk at this point, but they havent accomplished nearly as much in the division as Aldo did. GOAT is more a measurement of accomplishment , which means Jose is the FW GOAT. How do you measure GOAT and what other instances of this can you think of, if any?
