You don't have the luxury of time when you need to get it fixed. It affects your suggestion even more than mine - I'm happy to assume Ramsey does have it in him when he X (matures, gets more of the sense/discipline of the role/gets back into top form/ improves touch-awareness, etc.), but you're looking for "internal solutions" aiming to "control games for 90 minutes". I don't think we have at this point anyone who can do that the way we all want, but at this time dropping Santi for Art (or Jack) is just mad. There are aspects (and perhaps specific parts of games, maybe even specific games) in which Art (or another) can do a job, but in the bottom line it is Caz and Ramsey.
