< What I would do and what might happen are two different things. If it were up to me, Wells would be benched, if not cut outright. >
Therein lies the problem, I have a feeling that the decision of what to do with Wells ultimately lies with Arte. About the only thing that Scioscia can do is play him, and if (when?) his play isn't better than the players he is being played over, all Scioscia can say is "see, what do you want me to do with him?" and let Moreno make the decision of what to do with him.
I doubt Scioscia is going to bench Wells for more than a game or two at a time without having permission to do so. It won't stop people from basing an unjustified opinion about it though, some already have their opinion and it hasn't even happened yet.
