Campusano is a guy you might be able to get in round 3. And I definitely don't buy into the thought that we have to end up with at least one pitcher out of our top 2 picks. We've focused on pitching almost entirely at the top of the last 2 drafts, I'm totally fine if we go hitting in this draft, and I like the hitters available more than the pitchers.
That's why I'd want to grab one early to be honest - I think there are enough interesting bats available that you try to load up on them in rounds 2-6 if you don't grab a high ceiling gamble like Lewis, Beck or Adell at #5. If I could add one more high ceiling arm there (Gore/Baz/Bukauskas/Faedo) early, I'd be perfectly fine with trying to scoop up Vientos/Waters/Rooker/Campusano/Evan Skoug/Ward/Ramirez/etc. with our next handful of picks.
I completely get what you're saying about the pitching, but will always default to high-upside arms when there's not a bat that's really separated himself available at the same spot personally. Hard to get us old-timers who bought into the "Braves Way" all these years to change much, I'd guess.
