Over the last number of years, there have been a number of Japanese ball players who've managed to command millions of dollars just for the privilege of having a conversation with them about possibly signing a contract to play for an American ball club.
Once they receive this bounty, they often negotiate a contract guaranteed them many, many more millions of dollars. Then, for the most part, they end up being sub par players not worth any of the money they've been paid.
So, what's the deal? there are probably several factors that apply in some combination but in a nutshell, the game in Japan is different, it look the same for the most part, but it's different enough (structure of ball parks, pace, etc.) that stats alone are misleading.
So I find this interesting in that I am constantly complaining about how I hate that professional sports has become more of a business than a sport then here I allude to the less than business savvy of the same folks.
