Do you think that Boras and A-Rod just have a handshake deal on representation?
We have a couple of real estate agents who post here--ask them what happens if you sign a listing agreement giving them the exclusive right to market your house over the next 90 days, and then turn around and sell it on your own during that time frame
A-Rod will likely owe Boras his percentage, and by signing for less money, he's really shooting himself in the foot.
