I didn't find juggalosteve very funny. He appeared, to me, to be an obvious alias.
Everyone has their own idea on SSS. I generally stick with my initial line-up for about 40 games. If a player isn't cutting it, he'll likely go to the bench and become a platoon guy. That's assuming I know he's a big league player. If he was borderline, in my mind, to start with, I'll just send him to AAA after about 100 AB. Of course, all that assumes I have a suitable replacement. If I don't, I might just let him play all season. Like this guy:

He's up and down. But I believe he's a legit BL player so he's getting his 500 AB.
