Ultimately, Hamels' value is unknown on July 3 - 28 days until the deadline. It is totally dependent on the rest of the market. If the Milwaukee Brewers declined to make Zack Greinke available, Hamels' worth would increase because he'd be the only elite pitcher available. If the New York Yankees decided a rash of injuries to their staff necessitated the acquisition of another top arm, Hamels' worth would increase because teams would have to outbid the Yankees. And on and on.
