Ugh. I really like the rotation going into next April. It might be my favourite crew of guys that I can remember.
That said, I still wonder about making a trade of one of the guys you mentioned to fill an OF hole or something. It's Shatkins who can find a deal there if it exists. Maybe a pitching-starved wannabe team gives up something worth sticking in the outfield that makes up for the loss of stability to the rotation. I think only Happ gets that done, though, with Liriano being a wild card and Estrada having back issues.
