I guess AA this season will tell the story for Crawford, who just turned 20 a few days ago. If he has the same success he has had in A-ball in AA he will be a top 100 prospect on everyone's list. What's not to like about a speedy, + defensive CF who posts a near-.400 OBP with a .130 ISO? Fangraphs would get on board quickly, even if his ceiling isn't perennial all-star.
It's pretty impressive that he's hitting 300 and OPSing over 800 in 'high A' with serious swing issues, honestly. It gives him something specific he can improve which would make his production jump, and some players don't have that.
