I don't see #1 as petty discipline necessarily so much as it is means to the end of him falling down the depth chart that he is interpreting as punishment. Voluntarily workouts aren't meant to be hazing, they're meant to get your body into shape earlier. If three guys are all around the same talent level, and A and B went to voluntary workouts while C didn't, it would stand to reason that A and B would be further along in being prepared for the season come week one.
I could see him being told he was going to be a healthy scratch simply because they saw a better chance to win with others at the position. If he was passed on the depth chart by guys like Levi and/or Benito Jones, who were at voluntary workouts, and Buggs asks why they are seen as better than him, he could be honestly told "they are working hard, they put in the extra minutes at voluntary workouts, and right here / right now, we think put us in a better position to win against Kansas City." ... To which Buggs would say, that's BS, I only wasn't there because my kid was being born.
