I am 100% supportive of Coach Wardle, but that doesn't mean I agree with everything. I disagree that the Elijah Childs issue was handled the best way. I actually think it humiliated the player more than any post-game comment could have.
In fact, if I really wanted to embarrass and humiliate a player, especially one of my best and most productive players, I would bench him in a crucial, nation-wide television broadcasted game for the entire 2nd half, make him sit there and never get his warmup off, and then refuse to give any explanation afterward, other than "coach's decision". By doing that, everyone saw it and assumed the worst.
There are other ways to discipline or send a message to a player like making them run extra laps in practice, extra weight sessions, or many other ways, including depriving him of a sandwich on the bus trip home as long as he isn't hypoglycemic (ok, that last one was a joke).
