Update: Jason Marquis has signed with the Washington Nationals, 2 year 15 million according to Buster Olney. He was originally looking for anyone with a pulse to give him a 3 year deal, but the market never shaped up, and he's probably smart to sign now.
I don't see a whole lot of chance for Marquis to outperform that contract, so I'm not going to beat up Omar for not signing him. As I've discussed previously, he's a 4th/5th starter.
Remaining free agent starting pitchers of interest: J Piniero, B Sheets, C Wang, E Bedard, with the last 2 pitchers not being ready to start the season due to surgery.
