The point the writer was making is that Mitch SHOULD have known BEFORE he hired him. That was the point. Clyde's true colors were apparently no big secret in College Station. But the mistake was corrected quickly, I'll give you that. Although firing Billy Gillispie may have been the easiest decision ever made by any human being in the history of the world.
Oh, I got the point. But it was still written after the fact. It's much easier to review the past and pass judgement.
But again, knowing a lot of collegiate and professional coaches, abusing alcohol, abusing players, and generally being a jerk is so unbelievably not rare.
