Let's say the 10 best. Any sport goes, contact sports/team sports/Olympic sports... this is a thread all MB sports fans can post in and put arguments forward for your chosen sport and s
hit, whether you're a football fanatic, a cricketing connoisseur or an avid follower of handegg

. Maybe post examples of said sportsman showcasing their greatness.
Some obvious candidates to get the ball rolling:
Sugar Ray Robinson (Boxing), Lionel Messi (Soccer)*, Usain Bolt (Sprinting)*, Michael Jordan (Basketball), Ronnie O'Sullivan (Snooker)*, Roger Federer (Tennis), Tiger Woods (Golf), Phil Taylor (Darts), Don Bradman (Cricket)
* = Ones I agree are #1 in their sport. The rest are there for discussion. Some sports are maybe not athletic enough to be considered for this type of list (snooker & darts). There's a bunch of Olympians and other names I've seen like Wayne Gretzky and Jim Thorpe but don't know enough about these to argue or form a real opinion.
I would include Messi and Bolt in a top 10.
