Let us assume Adam James is a 20-year-old punk, as many stories indicate, who was using the sunglasses-treatment of his mild concussion as an opportunity to cavort around on the sidelines and generally be a ****. The way to deal with this situation is the same as you would deal with any unruly player: you dismiss them from practice. You tell them you can't coach them currently, and if they are not being coached, other players who are being coached will probably earn their playing time. This is what BB did when he recently sent 4 late players home from practice; he did not put them in a room with a bunch of ticking clocks to teach them the value of being on time.
The way Leach handled the initial situation confused his role as a coach with that of some kind of lawgiver, and it confused Adam Jones' injury with his lack of coach-ability. The most important aspect of this or any other disciplinary matter is what it says to the other players on the team. Leach's way tells them injuries — specifically, concussions — can be used as punishment for an offense, or might even be considered an offense in themselves. BB's way tells players that practice and coaching are privileges effective players should attempt to utilize as much as they are able. If Leach had merely told Adam James to leave practice and further reduced his playing time, no doubt he'd still have to deal with an obnoxious parent. But Texas Tech would need other grounds to fire him, and Craig James would have to content himself to making snide or offhand remarks about Leach on air, like Tom Jackson does with BB.
If we are to take Adam James' actions in this matter (and those of his father) as evidence of everyday systematic malfeasance, I'd take Leach's method of handling this the same way. It implies to me he runs a system based on control instead of on participation, which is how the rest of college is run.
