OK, well, Max tends to say some things that are "not in evidence", as we touched on recently with his "Dombrowski wanted to keep Betts from the Dodgers" comments. I don't know about the other people you're referencing.
No one can honestly claim that the Braves knew anything about Sale that the Red Sox didn't. I assume they did know more than us because they had access to Sale's medical records, but that's about it.
