Buchholz is a buy low candidate for some team. He's a guy with ace stuff, and a very flexible contract. There are a whole lot of warts, but teams will go to great lengths to try to find a #1 pitcher. I am not saying he is, or has been a #1 pitcher at any point in his career, but we have seen flashes. Remember that just 14 months ago, this guy was having the best season of any pitcher in all of baseball.
I would imagine some team is going to be willing to take the risk on his contract. Realize that in 2014, Josh Johnson was coming off a 6.20 ERA, and came away with a 8 million dollar contract this year. Johnson seems like a perfect comparison here. The Red Sox won't get prospects for Buchh, but they may be able to dump the contract -- there was some clamor over Buch being claimed off waivers.
