The high school kids have a lot of upside, but its hard to argue for a HS kid with so much talent at the college level. I have no facts to back it up, but Id be willing to bet more HS arms have flamed out than college kids. Pitchers can get hurt at any time, and a HS kid his first couple years is pretty fragile. Gotta build up the arm strength and other pitches, while watching an inning limit, as the kid is still developing physically. There's a lot going on there. The college guys aren't finished products, but their bodies are closer to being done maturing. They've grown as ball players from being 18 and pitching in high school.
Certainly, guys like Kershaw, Taillon, Beckett, etc. Those are elite guys you take. But when you have a slew of arms like this year(mentioned as potential top ten picks: Hultzen, Bauer, Cole, Purke, Barnes, Jungmann, and Bradley) its hard to go for a high school arm. The college kid could help us within two years. Not saying Bundy won't be under consideration, just saying, I think the team is leaning in the college direction.
