Will never ever happen, the players union is way too strong for that, you'd have to have the sport go through another downturn and a commisner who isn't a tool.
To be fair to the yanks though they don't win every year, only what 28 championships out of over 100?(yeah yeah, there isn't anything else like it, the next is what... the celtics with liek 12?) the only reason they spend so much though is because they make so much, with the yes network and the new stadium.
Also Selig fucked up that call with not giving that kid a perfect game, I don't understand him and most of the choices he makes it's like he enjoys being behind football(he is behind b-ball yet?) and refuses do try and one up them, hell the NFL doesn't even give a shit anymore about they, I think this year there is a football game during the world series(and it will destory it as well) you think there is any chance the onwers ever get a real comis?
