Trust me, it
Trust me, it would take a statement from someone with far more intelligence than you for me to take being called 'stupid' seriously. Not only are you an ill informed child, you continually increase your stake in one of the biggest clown shows this board has seen (which is saying quite a lot).
Again, consider the possibility that it isn't always on the coach if a team doesn't reach expectations.
In most cases I would believe that either this is some schtick or you're trying to be a troll, but you've made it clear that you would need an additional 25 IQ points to pull either off. You're merely a sad, simple child who believes he has far more insight and knowledge than he really has.
