Also, no golfers. Golf is not a sport.
10. Alex Ovechkin. He now has 658 career goals, 3 Hart Trophies (1 this decade), a Stanley Cup and a Conn Smythe Trophy.
9. Madison Bumgarner. A 4-time All-Star and a 3-time World Champion, his World Series ERA is 0.25. That's even better than Mariano Rivera.
8. Carli Lloyd. 2 World Cups and 1 lost Final, including 9 goals, including 3 in the 2015 Final. 2 Olympic Gold Medals (1 this decade).
7. Patrick Kane. He's knocking on the door of 1,000 career points, will almost certainly finish with 400 career goals and has a shot at 500. He's made 8 All-Star Games (7 this decade), and won a Hart Trophy, a Ross Trophy, and 3 Stanley Cups.
6. Usain Bolt. He's won 8 Olympic Medals, all of them Gold, 6 of them in this decade, including 3 straight 100 meter finals, making him the unofficial "World's Fastest Man" 3 times.
5. Novak Djokovic. Roger Federer and Rafael Nadal battled it out for the honor of the greatest male tennis player of the last decade, but Joker is the best in this one: 6 Australian Opens, 5 Wimbledons, 3 U.S. and 1 French.
4. LeBron James. In this decade alone, an All-Star every year, 4 MVP awards, 3 Finals MVP awards, 3 World Championships -- but also 5 Finals defeats, which prevents him from getting any higher on this list.
3. Steph Curry. 6 All-Star Games, 2 MVPs, 3 titles, and, more than any other person, turned the Golden State Warriors from an afterthought franchise into a historical NBA powerhouse.
2. Serena Williams. In this decade alone, 4 Wimbledons, 3 U.S. Opens, 3 Australian, 2 French, for a total of 12 majors. Overall: 7 Wimbledons, 7 Australian, 6 U.S. 3 French, for 23. Think of it this way: Venus has won 7 majors, which is great for almost anybody, and she's not even close to having the most in her own generation of her own family.
1. Michael Phelps. In this decade alone, the greatest swimmer ever has won 9 Olympic Gold Medals and 3 Silvers. Overall, 23 Golds, 3 Silvers and 2 Bronzes.
