This is an area where football parallels real life. Anyone who has managed a group at any level is accountable for their subordinates performance.
If you can't teach a member of your team while exhausting all avenues, and that team member is costing you dollars, football games, whatever...he needs to be removed or punished in a suitable manner. If you are a garbage leader incapable of presenting material in a manner that your team can learn and apply, then YOU are the problem.
Either way this is not a ref. problem, it's a problem that lies within this organization. I've seen plenty of calls this year go in favor of our team where I'm sure other fanbases were throwing **** at their TV's claiming that the Cowboys get all the calls.
