Don't know why a point is being made about whether a player would prefer a gold medal to a major. Some say the World Tour Finals is more prestigious than an Olympic Gold because only the Top 8 players are involved. However, the Top 8 players are usually vying for the Olympic Gold too, along with 56 others. Another point of difference is a loss during the Olympics makes it impossible to win the gold. A loss, or even two losses, during the RR in the WTF still gives a player a chance to win the whole thing. The World Tour Finals is an exclusive tournament where you have to be ranked #8 (or #9 sometimes) to even enter, meaning a handful of QF and SF appearances in Masters 1000 and Majors, so it's hard to qualify for this tournament. The Olympics are held every four years so a player has one maybe two windows of opportunity to realistically win it.
People point to Mecir, Rosset and Massu and mock that the OG can be won by nobodies. Mecir AFAIK
has won as many Masters 1000 as Tsonga, Ferrer, Berdych and Del Potro combined. As for Rosset and Massu, I believe this just indicates that, as in any normal tournament, a player can get hot and win the whole thing on any given day. Who won the Rogers Cup in 1997? Who won the AO in 2002? Who won Rome in 2003? Who won the FO in 2004?
At the 1992 Olympics Rosset beat Ferreira (SF at the AO, W at Queens Club), beat Courier (W at AO, W at Rome, W at the FO) and Ivanisevic (F at Wimbledon)
At the 2004 games, Massu beat Andreev (F Gstaad, 4R at FO), beat Spadea (4R at Wimbledon), beat Moya (W Acapulco, Rome, BA), beat Fish (F at Halle)
It's not as though the Olympics were attended exclusively by nobodies pre-2000 either. Just look at some of the named entrants who played in those past Olympics - even though some were demonstration sports.
1984 (Edberg, Cash, Muster, Forget)
1988 (Edberg, Ivanisevic, Masur, Leconte, Gilbert)
1992 (Edberg, Ivanisevic, Courier, Sampras, Becker, Stich, Chang)
1996 (Agassi, Ivanisevic, Bruguera, Henman, Rusedski, Philippoussis, Costa, Enqvist)
That's not including the women's elite such as Graf, Davenport, Capriati and doubles specialists like the Woodies. When you get into the 2000s before the Fedal era, with names such as Safin, Kuerten, Hewitt, Kafennikov, Henman, Ferrero, Rios, Rafter and Chang, the entrants start to look like names you would draw on a major, or at least a Masters 1000. The Olympics lack the history of the majors and as such this achievement is difficult to quantify and equate to the eras of Laver and Borg however this doesn't detract from it's current importance.
