I could see Boston throwing way too much money at him for him to ignore, but the last guy they signed for big money from the Angels exploded on them, so there could be a worry. If I'm Haren's agent, and he is let go by the Angels, I find the NL team who would give him a one year, $10-15M deal to regain his value, then hit the market for one last "big" contract at 33. Boston will probably throw at him a 3 year 30+ million dollar deal. He would more than likely have a bloated ERA in the AL EAST, so if he is smart he would go somewhere else.
