If we were to put today's conditions, which are overall much slower than they were in the 90s/80s/70s, who do you think would be most dominant in their respective eras? 90s Era : I say Agassi; he's a great slow HC player, and everything today looks to play like a slow HC. Although I think he would have stiff competition from the likes of Chang and Courier, both who are pretty good on slow HCs too. I didn't watch much tennis of the 80s/70s era, so someone will have to do this part. I would imagine it would be Lendl / Borg though.
