So I was thinking about this the other day, but how much of an effect do local taxes have on a football players decision of where to play? If Mario Williams is thinking about going to the Buffalo Bills, then he has to factor in their excess taxes compared to how much he would be taxed in Texas, which I assume would be lower. If you are trying to get the most money, then it's not just about getting the highest contract, you have to factor in taxes as well.
