Ober is good and I like him, if he's your first line of depth at AAA that says good things about your depth, not bad things about Ober. I'm pretty high on Ober, and I think he may well out-pitch someone in the opening-day rotation this year, but he's less proven than the guys in the opening-day rotation, and you can't stash Maeda, Gray, Mahle, or Lopez in St Paul. I'd rather have six starters I trust than five, and one of them's gotta wait his turn, and it has to be either Ober or Ryan, and while I like Ober a lot, Ryan pretty obviously has the edge.
(unless they try a six-man rotation again)
