During rumors flied around, I laughed at the idea pull off the offer to CC or set up a deadline when many Yankees fans or experts were pissed off CC's action which he didn't accept Yankees' offer immediately. Someone even said Yankees were being used and they embarrassed themselves.
I agree with the idea which let the player go if the player don't want to be here no matter how good he is. That being said, Both parties during negotiation need to know their positions. Even though CC really doesn't want to be a Yankees and use Yankees' offer to get Californian teams involved, Does do Yankees any good to pull off their offer to CC?
Of course not. First of all, some people just don't like to be forced to do or accept something. I remember I had a self-study section at junior high school and teacher asked us to study maths. Do you guys know what did I study? Originally, I was planning to study maths, but I decided to study history once teacher forced us to study maths.
Secondly, What do you think agents for Burnett, Sheets and Lowe will react when they heard Yankees pull off the offer to CC? They won't be in a hurry to help out Yankees. Instead, they may just ask for more years and more money. That's why Yankees couldn't pull off their offer or set up a deadline officially even though they know they are being used.
