This piece from last year includes quotes from his manager last year covering that question. Here's some of what he says:
"You're talking about one of the more interesting hitters, probably, in all of the Minor Leagues," Threshers manager Greg Legg said. "He barrels up balls over and over again. He does have a lot of early contact, but he also gets a lot of two-strike hits. "He has the ability to handle the bat and hit it wherever he wants. The bat control that he has and the eye-hand coordination is off the charts. He manipulates the ball. I never played back in the Ty Cobb era, but I can only imagine those are the types of things he was able to do."
"He can catch," Legg said. "His hands are soft. He blocks balls and he has a feel for calling games."
"Everybody in baseball is looking for a guy who has a cannon for an arm and is picking everybody off and you have no chance to run. He doesn't do that. But the two years I've had him, whenever something's been needed to be addressed, if he decides he wants to do it, he's capable of doing it. So in my mind, he's capable of improving his arm strength and his times to second. He's really caught well in the second half when we needed him to."
The latter quote covers the catching question, time will tell how the Braves grade him in that regard and if his bat will be good enough to seriously consider him.
