Fangraphs isn't a great prospect resource right now. They aren't dumb, but they are slow to update - I try not to use FG unless they're an outlier (for example, Logenhagen was the high-man on the pitcher that went for Shane Bieber at the deadline - but that's also around when FG updates things). As well, the Orioles have a super-deep system and guys like Bassalo are still on the list, even though they're MLB players now (he just still has "prospect" status due to a lack of PA).
Instead of using FG's prospect rankings, use this article, also written by Logenhagen.
This is a significant return for Baz. Caden Bodine had first-round-hype and fell because of signability more than talent, Slater de Brun got the highest bonus of any non-first round pick in the same draft. And there's a Comp-A pick.
The Rays just essentially got three first round picks + two other prospects for a pitcher who has some cool under the hood stuff but hasn't put it all together, despite being with the Rays (a good pitching team). Don't get me wrong; I like Shane Baz! But this is considered an excellent return by the baseball community.
