Yes to Bo Jackson and Deion Sanders... I think they both are so much above anyone else on these list, I will just leave the next three spots open until some athletes come along that are at least close in athletic prowess to them.Bo Jackson (multi pro sport successful player)
Deion Sanders (multi pro sport successful player)
Michael Jordan (almost went multi sport)
Jesse Owens (to do what he did in the times he did it was a huge feat)
Michael Phelps
