There seems be be an inevitable acension of the Olympics as a big thing in analyzing careers. It seems to have really picked up during the 2008 and 2012 Olympics.
Previously, it was seen more as icing on the cake, maybe a way to distinguish players who were otherwise similar, but really not that much more. I mean, obviously, the Olympics, overall, is incredibly prestigious, but it wasn't really that way for Olympic tennis through the first few tennis events (due to lack history, and to the fact that tennis already had its own most pretigious events). This is not to say that Olympic gold wasn't an impressive feat, or that any particular player shouldn't consider his/her gold to be among their finest acheivements. Lindsay Davenport, for example says she considers it an accomplishment on par with her majors. But, that was always up to the indivdual palyer. Many fans and commentators didn't really view Olympic gold as essential or more valuable than a WTF title or really that essentialin the overall picture.
I'd agree with this personally. I feel the Olympic tennis kind of rides the coattails of the "Olympic" brand, and because the Olympics really is the biggest, most pretigious accomplishment for most Olympic sports, that was bound to spill over to tennis, regardless of its independent-of-Olympics nature.
I have no problems viewing Olympic Gold as a great accomplishment, because it is. But, I do sort of think it's overblown, especially considering the format of the tournament, which isn't anything special or different (like if it were a true multi-gender team event, or had pool play like the WTF, only bigger (4 pools of 8, or 8 pools of 8, or some other combination), or if women played a best of 5 final) than any other big non-Slam event. And, with the player restrictions per country, the Olympics can even be a weaker field than a Masters.
But, as I said, it seems like the ascendency of the Olympics as a tennis accomplishment and Olympic gold really mattering to GOAT discussions or debates about who had a better career, is well established, and I really don't see anything turning that momentum around. It's hard to argue with it because if you question it's importance or relavance, all any one has to say is "Because it's the Olympics" and most people won't even question that because generally Olympic gold is seen as the ultimate in athletic accomplishment.
