Yeah, it would be fine to keep Hardy for 3B in the future. I just don't see any logic at all in moving him there now.
Yeah I was spitballing thinking that next year he'd have to move right about this time of year anyway, so maybe the tradeoff of offense to defense was worth it as bad as it's been this season.
I don't even get how that's the tradeoff you thought of, though.
It's way easier to move Andino to 3rd instead of SS imo, and I think it would be more effective, and it wouldn't tick off one of the better players on the team.
