In your quest to insult everyone on the board, I'm reading this a little differently than you.
Austin Riley is hitting a solid .309 or so in Class AA at an age that many of his contemporaries are struggling to escape the SAL. His defense has been solid since arriving in AA, and if he fields the ones he can reach, it doesn't matter if he can't reach everything. Acuna's numbers aside, Riley's performance (interpret it however you wish) make him one of the most promising power hitters the Braves have developed this decade.
It might make for a more boring board, people, but comparing players who you have seldom, if ever, seen in action only makes you look like the casual fans you are. You'll enjoy posting a whole lot more if you don't overreach and pretend to have great insight.
And those of you with great insight, it's OK if you go a day or two without reminding everyone of this.
