at least the referee had conviction and confidence about his throwing a yellow. Coaches need to shut-up anyway.

One of the beautiful aspects of the game is that so many plays can happen in very different ways. It's almost an "art" to be a good referee. In one instance a foul might be severly punished, in another the ref might let it play-on

Ah, "Advantage." Off the topic, but I wish more refs would call the advantage and let play continue when the foul *clearly* does not hurt or slow down the other team.
