Well Corbin is 3 years older, was a 2nd round pick, and had a K/9 rate in the 8s until this year.
Since May 11th, which is when Tailon added his new pitch, the kid is sitting at: 141IP, 137SO, 8.72K/9 with a 2.93ERA. As far as being hittable goes, you're bang on. But I think that has a lot to do with age and figuring things out (remember, still 26, was a 2nd overall pick, added a new pitch which changed him immensely, had a 3.38ERA in his debut year).
He's 100% a top 20 pitcher next year, and I could see him finishing in the top 15 if he keeps it up. Nola and Corbin are guys I like, but I think a Nola comp is more appropriate as to what Tailon will/could become (although Nola's BABIP scares the crap out of me). In the end if you miss out on Nola and Corbin and get Tailon as a consolation prize, I think you'll be pumped.
Hot take for 2019:
209IP, 195Ks, 3.25ERA with a WHIP of 1.10, bad record (something like 11-11 or whatever) but everything else is great.
