Formerly known as, "The A-Rod Question".
It's easy to find athletes we don't like. For some, there are personal reasons behind their dislike. For some, they just don't like the way a guy/gal looks or acts. For some, they just disagree with choices they've made. All are valid reasons, because sports don't require true rationale. What we feel about sports is what we feel, and no one is required to explain themselves to anyone. The great part about that, is that it can lead to some very strange grudges.
Personally, my feelings on my least favorite player have changed as time has gone on.
