If you're going to keep Buxton in AAA because you don't think he's ready, it doesn't make sense to roll with Santana in CF after his awful, miserable season. The only way that arrangement makes sense is if the reason to keep Buxton in the minors is service time. In my opinion, without Hicks, you have to give the job to Buxton, ready or not. It won't kill him and it likely won't be worse than Santana out there.
