Gavin Floyd is reportedly available in a trade. Floyd is one of the more underrated pitchers in MLB, although he certainly can have starts that go beyond frustrating. The guy can go out and give you 2 or 3 starts that make you question his presence in the Major Leagues, and then follow them up with a month of pure being purely unhittable. Overall, he ranks 29th among all starting pitchers in MLB in WAR over the past 3 seasons, ahead of Tim Lincecum. From 2009 to 2011, he was 15th.
He is a tough man to gage trade value for. His closest equivalent in a recent trade would be Edwin Jackson. However, Jackson is frequently part of very large trades, so it is hard to see how GMs value him independently. However, he was dealt as part of a side package with Mark Teahen for former Red Sox RHP Zach Stewart and Jason Frasor. Stewart’s inability since aside, he was a fairly good prospect in Toronto, but he was never in the BA Top 100. If the Sox could get Floyd for a package of Brandon Workman and one of the catchers, it needs to be done. The White Sox might prefer to climb the Sox prospect ladder a little higher, or potentially take a reliever as well. (Aceves? Melancon? Miller? Alex Wilson?) Garin Cecchini should certainly be enough of an addition for one year of Floyd, but one would hope it does not need to go that high. If Kenny Williams was in charge, the price would probably be a lot less, as he took some fairly bizarre deals. Who knows what to expect from Rick Hahn at this point, however.
It is worth noting that the deal of Jackson and Teahen for Stewart and Frasor was a Kenny Williams deal, and therefore might not be representative of how actual GMs value players.
