Your other issues don't hold any water for me. He's had 14 wins each of the last two years on a mediocre team, doesn't seem to be a problem. His K and K/BB are both above average with room for growth and he's a great GB pitcher with two plus pitches.
Yeah, I can't help but think Cargo and CoreDick both dropped a bit under the threat of that. Now it looks like the might just move CoreDick to 1B and keep them all, which makes sense.
