The moves you're referencing aren't really scout vs. stat moves. They were moves motivated by business considerations. Swanson was needed for marketing. The Kemp trade was made so we could get away from Olivera. Markakis was signed because we knew we'd be bad but still wanted to put a team out there that wouldn't be so bad as to completely alienate fans.
The problem isn't stat vs scout. It's business vs baseball.
Umm, when Kemp was acquired everyone with any analytical knowledge knew he was toast. The reasoning behind acquiring him was literally "our scouts think he has something left". Many on these boards agreed.
Markakis was signed as a way to appease the analytical illiterate faction of the fan base and the FO. It worked perfectly.
Swanson was promoted because the dinosaurs literally had no idea how much surplus value it would cost the organization. It was a spur of the moment idea by Hart with zero thought put into it.
Again, the lack of seeing what is really going on here is comical.
