I don't want to say I'm a CB expert, but I've watched him extensively since he was in Rookie Ball. Again, everyone told him he was the second coming of Benito Santiago. I watched him literally tell a pitcher (in my broken Spanglish dialect interpretation) don't worry about the runner on first base, he's got him. The guy took off and CB did throw him out by a mile....So he was lazy and relied on the "ARM" more than anything. He's learning though. I don't think he's as lost as people proclaim, nor do I think he's going to be Yadier Molina, but he'll be serviceable. Pitchers began to like to throw to him after some rough introduction.
Keep in mind this: Gattis is no catcher other than he's done it. Anyone remember the game where he and Teheran were essentially at odds and Teheran can be demonstrative so it shook him. Gattis tries hard. I give him that, but if nothing else, Bethancourt has very little to prove other than he's a backup or starter at the MLB level at this point. Framing pitches and calling games has always been a development point. As bad as you think he may be, he looks like Molina compared to Gattis.
