Dumb is what it was. The Reds player who got the red card was his own worst enemy. What purpose does he think he was serving by giving his opponent a facial. Was he trying to intimidate, injure, get a reaction, show what a [strike]hard man[/strike] boofhead he is? Officials are very wary about hands and fingers getting close to eyes. If you do what this idiot did, you are leaving yourself at the mercy of a referee/TMO/AR who might see something dangerous in it.
As for players, such as Horwill, who are annoyed at the TMO protocols, they might be complaining that they "slow the game down", but I don't think its really that which is bothering them. More likely, they are annoyed that players can't get away with the dirty, underhand and off the ball tactics as easily as they could in the past. The Deysel stomp in the Crusaders v Sharks game would not have been punished until after the game had it not been for the new TMO protocols.
IMO so-called enforcers like Bakkies Botha, Danny Grewcock & Troy Flavell would have been red carded a lot more than they were had they played under these protocols.
