who is the greatest legend in sports history?

who do you think is the greatest (male) hero in the history of all sports? as a die-hard sports fan my goal is to create the most complete and informative pool on the net, so I have done my best and I came up with this list, but if you think that somebody is still missing feel free to suggest me for any SERIOUS (so no jokes!) name that you think should be included by posting a comment here in the message area and I will add it to the pool, thank you
