All he’ll have to do is present the roster he was given and the other organization will nod and say, “Oh, right, that’s terrible.”
Sure, to some extent, they were never going to be great. And there's been plenty of injuries, but their payroll is right in the middle and several players who have/had potential and not just no name placeholders. We're not talking about managing a team that finishes a close last in the league. They are competing for worst record in the modern era, with losing streaks of 14, 21 and other notorious streaks. Can't blame it all on the roster.
