When they can the Braves usually deal players they trash as much as they have Bethancourt. They did the same with Gattis this time last year and despite claiming he would stay just before he was still moved. Further, they have continued to question Bethancourt's game calling abilities, etc. And they recently used Bowman to say he hadn't improved even though he clearly has both offensively and defensively. This along with other likely moves (like bringing back AJ possibly to back-up at catcher) tell me the writing is on the wall unless something causes them to change their mind.
I think its going to be different with CB honestly. These kids that they sign at 15/16 are like sons to the organization. Thats why I don't believe for a second they are going to trade Teheran.
