25. Sidney Crosby
Bonafides From 2002-2012: 8x Grand Slam Winner, 2011 ATP POY
Sid the Kid was supposed to be the heir to the throne. His game is patterned after the Great One and was on his way to save professional hockey in the States. Sadly, the NHL refuses to change its ways and now have to deal with the fact that their marquee player can't stay on the ice due to concussions. Crosby finally returned last week and so far looks healthy, but you never know with head injuries. He has helped the Penguins to two Cup appearances (and one win) in his young career, and if he can stay healthy, there should be plenty more where that came from.
