.. when Theo is talking about accountability and stuff that he's referring to Russell. He might be, but I doubt it. Everything I've read is that Russell has done almost everything the FO asked him to do. I think there's something else going on. Backstabbing, missing signals, swinging for the fences with winning run at third and one out, being clueless about game situations in one's hitting approach, nursing injuries...there's more to it.
Yes, I assume Russell did as asked for counseling, and yes to your main point that there's more to it. If it's just Russell, they could let him go and and problem is solved.
Russell is the face of the franchise for accountability issues, both on-field and off. On field, there was the stuff about not being focused defensively, having mental errors, AND not even having complete command of the signs. That's a professionalism/preparation issue. And down to Iowa he went.
Theo made a reference to "consequences", and used wording as if he thought everybody could see that somebody had been held accountable for something. What "consequences" was Theo alluding to in his head there? Russell getting sent to the minors, but what else? And if players experienced consequences, were they for performance, or for behavior issues of some other kind? Edwards, Almora, and Montgomery were bad players sent away; are those performance consequences that Theo was alluding to?
I kinda don't think so, because great club leadership doesn't make bad players good. What leadership is supposed to improve are issues of behavior, attitude, professionalism, preparation, practice habits, focus, etc..
So agree with Curt, there's more to it than Russell, and you mention some possibilities.
