Brother, if you want this team to fail in the hopes that someone gets fired, you are watching the wrong team.
Also, even signing Harper AND Machado wouldn't prevent this team from evaluation of player development. We literally have no 3B worth worrying about blocking, and while it would be interesting to see what you can get out of guys like Palka and Delmonico, none of them have a chance at being a star player, so really it doesn't matter if they lose time. We aren't talking about guys like Eloy and Robert being blocked here.
