Babcock seems to like the "safe" choice, hence Emmerton. But you are correct, we already know he can't deliver so why? I just don't understand his train of thought or lack thereof
Well, part of it might be a lack of difference in what they expect either to bring to the wings. Another part might what they expect either to get out of a very prominent role in GR, and what they might bring GR. Emmerton is who he is. More time in GR won't change that, regardless of what he's doing down there.
Being elevated to being "the" guy in GR could be big for Ferraro, though. It's more responsibility, it's more exposure, it's tougher match-ups. It might be a better way of tempering him for a full season with the wings next year.
I'd like to see him in Detroit, too. Not sure it's the right decision by Detroit, but that might be part of it.
