because they want the money? This isn't complicated - he wanted out of new york and boras told him he would still get the money. for pro athletes, it's either about the money or about the money. and if they say it isn't, they're lying What a terrible generalization. It's not always about maximizing the money for every athlete. Sure it is for many of them. But there are dozens of athletes in different sports that have taken less money (or restructured deals) to go to a team with a better chance of winning a title, or improving their teams chances of winning a title. Frequently, it's athletes in ARod's situation - have tons of money and the big name, but really want the ring. And in baseball, the Yankees give you a great chance to win one, but they certainly aren't the only team that can regularly contend for a title by adding ARod (and other teams come with less baggage than the Yankees do). right, so they really aren't being all that altruistic since they already have enough money for 5 lifetimes
