Justin Upton is a great player, don't get me wrong. But Acuna is a lot faster, plays much better defense, and in the long run will probably be a better hitter than Upton. The best WAR Upton has ever put up is 6.3 on Fangraphs and 5.5 on B-R. If I were a betting man, I would 100% bet on Acuna having multiple seasons that eclipsed that number. I think a better historical comp might be a guy like early career Andre Dawson.

I've seen enough of Acuna in the minors and early in the pros to think that he is quickly going to become one of the 5 best players in baseball.
