We've had a lot of discussions on so called weak eras in tennis. Some of the reasons are because they may serve as explanations for why one player may have done well in a certain era. If one player dominates it may have been because of the so call weak era. I do believe that just by logic alone, there had to be times in tennis history in which the relative quality of play more have been lower. However I do think it's hard to pinpoint and a so call weak era may be in reality a strong era. For example I do believe in Pre-Open tennis that perhaps there were very weak eras in the amateur ranks. Roy Emerson won a lot of majors in the 1960's and yet he may not have been one of the very top players in the world. Would he have won so many majors if Gonzalez, Laver, Rosewall, Gimeno, Hoad were playing in the majors? I would doubt it. But that was the times. The Pros had all the best players and while there were some strong players in the amateurs, there weren't of the level of the pros. So I'm curious what people consider a "WEAK ERA" and what is a "STRONG ERA" in tennis and why? Please don't just give an explanation that currently we have the strongest era in history just because it's the present. I want some explanations if possible. Obviously there is no right or wrong answers here. No one can prove anything but it would be interesting to see the explanations and perhaps learn from them.
