I would not give up on Morton. He has no hit stuff every time out until his mysterious loss of command around the 5th or 6th. I think he still is adjusting to his new bionic arm/velocity, and with no knowledge, only observation, I think he also may be dealing with confidence/trusting his stuff issues. I think Peacock is more valuable as a bridge to Harris and whoever else gets us to Giles. Watching Hinch reconstitute the staff and pen will be interesting and fun. Fiers has to be the odd man out despite his flashes of really good pitching this year, and I cannot believe they will DFA Hoyt.
Kuechel, Verlander, McHugh, McCullers (BIG IF!), Morton would be my rotation with Morton in the pen IF we make the post-season. A lot depends on McCullers, and damn you, Angelos. Britton should be on this team.
Sipp, Feliz, Hoyt, Martes, Musgrove--we'll see how they do in September. My guess is Liriano will be there because of experience and LHP. He has the stuff for sure.
ETA: "The Astros gave up more than I would have" stuff has started in some of the blogging. Fuck them. I understand Perez and Rogers are great prospects, and who knows about Cameron, but these same people vilified Luhnow at the deadline for being in love with his prospect. The message is: no matter what you do, the Internet experts will come down hard.
