I might look at this a bit differently. We see many pitchers every year that throw in the low 90s. We have only seen one or two catchers in the last 20 years with that combination of velocity and pop time. So if he can hit and shows power potential he should be a highly regarded prospect as a catcher.
I suppose the thinking is about his ceiling as a pitcher. If he has just started, I suppose anything is possible. But right now he sounds like a catcher with a great arm.
