I can understand lament for not having "more experienced" backups when/if the replacement backup plays like the scrub you call him. When he doesn't, seems like a good time to just enjoy it. For whatever reason, you are apparently unable to do this, and you bitch about him being on the team, even while he's performing. It's misplaced. This is what I think you are being called on, and, quite frankly, it's deserved.
