re: Leach a good coach or not. Let history be the deciding factor. Let's chart the next time Washington State goes 11-2. I venture a guess that it will be sometime north of 10 years from 2018 before that happens again. If so, then yeah, in 2020 Leach would be considered to be a good coach, imo. Taking Washington State to 11-2 in 2018, I consider that to be a GREAT coaching job.
Now, Leach is one coach who definitely is aware of his surroundings. Sure he knocked the brawl off his shoulder, just like Robert Conrad would a battery. Why? Because he lives in the SEC, where...remember in the immortal words of Charles Barkley, "if you ain't cheatin, you ain't tryin".
He just won a bowl game, he doesn't care about how something may have looked, and he and his AD can always come out later and announce disciplinary actions for player or players to be delivered sometime in the future. Nobody in Mississippi will remember the negativity of the brawl. They will only remember Leach took a losing team into the bowl game and beat a ranked, winning team.
