I agree, Steve. And I would add that his hitting has provided hidden value. While it's not a skill you select pitchers for, the runs produced (or not produced) by pitchers at the plate and on the bases still count in the wins and loss columns. In his ~2.5 years worth of starts, Leake has produced 2.0 fWAR offensively.
Now, looking at his BABIP and his K:BB, it's quite possible (probably likely) that those numbers are a fluke and that he'll hit like a normal pitcher moving forward. But it should at least be part of the conversation.
