Let's start naming all the free agents (and former FAs) pitchers that have better career ERAs than Edwin Jackson, shall we? John Lannan, Mike Pelfrey, Jair Jurrjens, Scott Baker, Shaun Marcum, Zack Greinke, Brandon McCarthy, Joe Blanton, Erik Bedard, Jeremy Guthrie, Derek Lowe, Randy Wolf, Joe Saunders, Carlos Villanueva, Chris Young, Freddy Garcia, Kevin Millwood. There's a lot and while I wouldn't take all of these guys over Jackson, think of how much cheaper so many of these will end up being. Oh, and Liriano is tied with Edwin Jackson's career 4.40 ERA. Seriously, pretty much all pitchers besides Correia and some of the true scrubs are the only ones I could find with worse career ERA's than Edwin Jackson.
