Americans once ruled boxing's heavyweight division with an iron fist and a cast iron jaw.
From Joe Louis to Rocky Marciano to Floyd Patterson to Muhammad Ali to Larry Holmes to Evander Holyfield to Mike Tyson, Americans passed the heavyweight title belt from one generation to the next.
Now it's hard to find an American in the top-10 rankings, and the last American heavyweight champ was Shannon Briggs (not exactly a face on boxing's Mount Rushmore) in 2007.
American men also once dominated professional tennis. From Arthur Ashe to Jimmy Connors to John McEnroe to Jim Courier to Pete Sampras, Americans won Grand Slam events from Australia to New York. But the last U.S. man to win a major was Andy Roddick at the 2003 U.S. Open.
That's 38 consecutive majors without an American champion. And it'll soon be 39 with the United States reaching a new low at Wimbledon, where America failed to send a man into the third round for the first time in more than a century.
Tiger Woods is still the best male golfer in the world, but he hasn't won a major since 2008, and there hasn't been an American winner at a major in the past four tries.
So what does it all mean? Has individual professional sports in America declined, or has international competition simply risen and surpassed our athletes?

International athletes have caught up.
Combination of both.
