All I said was "it's something to worry about if he's going to try to stick behind the plate long term" which is what they said. They even talked about his bat needing to be good enough for 1B or DH.
I'm not out of pocket on this one IMO. They are higher on Johanfran because he's younger and still as advanced offensively. If he can stick at catcher, he has much more value than his brother. If not, the value goes down.
