Fortunately, I have no clue who half of these people are. So maybe they were/are overrated. But come on, Nolan Ryan, Pete Rose, and Steffi Graf? They are on anyone's all-time great list (or should be).
I'd replace Steffi Graf, pretty much the winningest tennis player in women's tennis history, with someone like Anna Kournikova, who translated her PR into a $100M fortune. Heck I'd even go with Margaret Smith Court as overrated, since she won like a decade or two of Aussie Opens with NO competition, before Steffi.
