Adrian Houser obviously hasn't been great this year, but he is coming off a year where he went 10-6 with a 3.22 ERA. Even with his down year, his numbers are very similar to Greinke's, and he's 9 years younger. Why in the world is Houser being thrown in with a AAAA retread like Alexander, let alone being viewed as someone who can be replaced via "serious upgrade" in Greinke? Greinke has had a great career, but he's 38 and is pretty much toast.
