Getting rid of Vaughn should not be a priority. Of all the 1st basemen in the league, he’s one of them. Probably a bad pick at 1-3 given the fact that Pasquentino was taken in th 11th round of the same draft, but he’s productive on a team with very few productive offensive players.
IMHO, this is going to take a massive organizational overhaul, so what happens with Vaughn one way or another is just not gonna matter much.
