I used to be a huge hater on Edwin Jackson, mostly because he was always kind of awful, then he put together like 3 1/2 good months in Detroit and somehow that parlayed him into a player nobody wanted to keep, but teams always tried to trade for, and gave up decent players as a result. Jackson was traded for Max Scherzer, Daniel Hudson, and Colby Rasmus over the course of about 1 1/2 years. I didn't understand it, but he started to live up to his potential consistently when he went to the White Sox and he's been fairly consistent since then. His fWAR since 2009 has been 3.6, 3.9, 3.9, 2.7. He'd almost assuredly be, at the very least, a 2.5 win pitcher, but more than likely a 3 win pitcher each season throughout the duration of the contract. He'd be worth the gamble, and I wish the Cubs would step up a pursuit. EDIT: Speak of the devil. Brett just put up a nice article on Jackson: http://www.bleachernation.com/2012/12/17/so-lets-talk-about-edwin-jackson/
