That is an interesting site. I'm not into astrology so I don't know what it all stands for. I especially liked the chart where you could chart his chances against other players based on their astrological signs.
I would not want to be checking in on this thing before a match. I am not sure just how much it could, or would affect my playing. Heck, if it's the stars that determine how I play, I'd hardly have to do anything.
I would think that many could end up being a jinx of sorts from what some end up saying. You know some fans all over the world have "lucky charms" for their favorite teams, so why not believe in this type as well?
