It depends. In your example (comparing it to baseball) one would likely require me to move. And if I have a family, I'm likely not going to move just to get an extra 20K. Plus there are other factors like lockerroom, quality of the team, fanbase etc.
I understand what you're saying. And that's why I'm not going to blame players for taking the extra money. (Let the record know I'm not blaming them) However, I think it's ok to say that 100M or so should be more than enough to live your life and that one shouldn't ever bitch about money when they are getting 100M+
I feel that your perception of the point I'm trying to make, and the point in my head I'm trying to make are different. Again I find myself in the middle on this.
