Couple things, 4.10 ERA is quite a bit less than Correias career numbers (many of which where helped in the NL/pitcher friendly parks) I would argue that Hughes has actually had 3 good (but not great) seasons in 2009, 2010 and 2012. Additionally I think a change of scenery could be perfect for him, before he ever pitched in the big leagues he was already being named the savior of the Yankees rotation, which is a TON of pressure, additionally the Yankees screwed with him a bit by moving him in and out of the rotation when he first came up. I think by going somewhere like Minnesota, the lack of media/pressure/bright lights could be beneficial to him (see Pavano?) additionally he does have pretty nice stuff and is able to strike a good number of guys out, his main problem has been the long ball, so there is a chance Anderson could help him out on that, and Target field would be beneficial as well. (Especially with a defense that could include Hicks and Buxton) for at least 2 of the 3 years of his contract. Could he not get better and just stay the same? Sure, its a risk, but unlike a signing like Correia, Arroyo etc there is a good amount of upside if things click.
