Thanks for the update - it's nice it's early and finding a substitute shouldn't be a problem. I know a few guys that would be interested.
As to Morrow, I'm certain he will end up with something like a S5/R3/C3 card next year, so he can be used as starter or closer. His relief ratings probably will be better than his starter rating, although I'm pretty sure he'll be a serviceable SP too.
And check your PM's - I'm sending you an offer
