While the Australian women look to be strong in trying to fend off the threat of an improved US women's team, some forecasters see a tough Olympic Games for the Australian men.
Their one strong gold-medal favorite in an individual event is James Magnussen in the 100-meter freestyle. Countryman James Roberts could take silver.
Known as the "Missile," Magnussen, who is the current 100-meter freestyle world champion, makes bold comments and doesn't shrink from them – like he can win the 100 meters and set a world record so long as he is at 90 percent.
No Australian man has won swimming's blue-ribbon event since 1968.
