Lodolo in the latest FG mock certainly seems to be a case of BPA, so we can't really be upset if that's how it shakes out. This is the comment they made in the mock:
"We just think this would be good value here, but Lodolo is polarizing and could get to 13th. They’ve scouted Bishop very heavily, Rutledge is in play, Priester is a sleeper here, as is Hoese either here (under slot) or at their next pick. Langeliers has also been mentioned."
Perhaps if Lodolo falls to them they consider him BPA and will pop him, otherwise they will go underslot bat at 9 and try to float an above slot arm to 21.
Of all the reasonable scenarios I've seen the last 2-3 weeks, I think I prefer college bat at 9, and then Priester at 21 hoping he is a cold weather arm that can add stuff similar to what Soroka did.
Sounds like the Braves have a clear Plan A, B and C, which is good to hear.
