Jeff Sullivan at Fangraphs was asked about what Machado would bring in trade with 1 year left. This might be useful to compare to Bryce:
I'd say Machado is extremely similar. While his bat is not as good as Bryce's, his defense is far superior, and the fact that he could play shortstop only increases his value. I also agree with Sullivan. I just don't think you're going to get that blue chip, sure fire prospect. You might get a decent one (like a Fedde or a Soto) and some intriguing ones. But I can't see a team giving up a Moncada, Robles, or Byron Buxton type.
