I think it's hard to really pinpoint these guys down to an exact slot. I think there's a general range where a guy fits in. Hickey feels adequately placed when surrounded by Binelas, Wong (who is making the case for being the BOS backup in 2023) and Ward. Kavadas seems to fit in with Drohan, German and Bonaci. With Hickey, I think there are still questions about his glove and if he can stick at Catcher. With Kavadas, he seems to really be a DH only profile which is why he's 29th rather than knocking on the top 20 door.
Because Seabold has good control, he can dominate AAA. The problem is, his stuff isn't good enough for the next level. Until I see it work there, I'm not sure I can believe in it. Think of Denyi Reyes in 2017-2018. He breezed through the low minors because of his control with ERAs in the 1's and low 2's. https://www.milb.com/player/denyi-reyes-660593 He eventually hit the wall where his stuff couldn't play up anymore. He has been getting smacked around in AAA this year in BAL, but has made some brief appearances for their MLB team (even starting in Fenway on 5/28).
