Regarding double standards, that is EXACTLY how things in the real world work and how they should work. The more valuable you are, the more you can get away with. But besides that, there is hidden information behind what DOC said. That is, he knows that KG can handle himself, even if he does get a tech.
This is very similar to Jimmie Johnson's philosophy (Cowboy's coach). And he never hid it one bit. If you fall asleep in the meeting room and you are a star, you get run all day in practice. If you are average, you get cut.
And players believed in that as well. I remember hearing a story where Barry Switzer cancelled a practice because a bunch of players were hung over from partying. Troy Aikman was p---ed. Switzer's response was basically, what do you want me to do as Michael Irvin held the party. He asked did Troy want Barry to cut Irvin?
Aikman's response. No, but you cut that guy and you cut that guy and you run Irvin until he is puking on the field.
This is the USSR. The point isn't to try and equalize everyone. That is the way it is.
