If you can pick ONE athlete ever to have an injury-free career (from beginning to end), who are you choosing? I would pick Ken Griffey Jr. Hard to believe that he wouldn't have broke the homerun record if he had stayed healthy. Was never the same player after he left Seattle. Bo Jackson is by far the most popular answer in the comments. Who would you guys like to have seen play with an injury free career? Since it seems like everybody only named pro athletes, let's take it one step further and include college athletes too.
