If you evaluate Beer as a potential elite hitter (and I don’t know if the Braves do or should), there’s an argument for taking him at 8.
The most obvious comparison would be the Brewers using a top 10 pick on Matt LaPorta when they still had Prince Fielder at first. They made noises about trying LaPorta at other positions, but predictably they ended up dealing him (for CC Sabathia), which isn’t bad value for a draft pick.
If Beer rakes, he has a ton of value. You can trade him. You can try him in left and see if that’s actually a possibility. And if you keep him in the minors to develop through 2020, then Freeman has just one more year on his contract, and you can potentially use Freddie as a dynamite trade chip, finally fulfilling Horsehide Harry’s dearest dream.
