He's 20...in high-A, it's not like anyone is saying he's on Tiedemann's level or anything. Cleveland's market inefficiency and what makes them so good at pitching dev is most of their pitching freaks are boring college pitchers who throw lots of strikes with okay stuff and somehow they get them to be strikeout monsters. Toronto will already draft the big power arms early - guys like Pearson, Manoah, Ricky Tieds, Barriera, Nick Frasso even - although IIRC Frasso started out as projectable arm, the big velo didn't come until later. I wonder how differently the pitching dev would be viewed if Pearson wasn't made of paper mache. Just because Berrios, Kikuchi were garbage last year doesn't mean the org targets soft tossers with "pitchability". Both of them are guys with good stuff, ditto Gausman and Manoah.
They've also gotten career years out of Robbie Ray, Steven Matz, Ross Stripling and sold/let them go at the right times. To some extent that's a skill, it's just annoying and unfortunate that they haven't been able to develop these kinds of arms themselves. It's why I haven't given up on Mitch White yet, the org has found success with players of his ilk in the Shatkins era.
