I was thinking the same thing. Without meaning to condone the comments by Matterazzi, it doesn't seem to me that he did anything that isn't a tacitly accepted practice in football (both kinds), basketball, and undoubtedly many other sports. At exactly what point did Matterazzi "cross the line" and do something warranting a suspension? By engaging in smack-talk with Zidane? By using profanity? By directing the insults toward a family member rather than the opposing player himself? What if he had told Zidane "you're getting slow, old man, you can't keep up with me anymore"? What if he'd said "Zidane, you suck." What if he'd used a homophobic slur toward Zidane? What if he'd brought up the surrender of Paris? What if he'd offered some abstruse but intellectually stinging insult about Camus' The Stranger that could be construed, in part, as a comment on Zidane's Algerian ancestry? What if he'd said, "Zidane, your mother wears combat boots"?
To me, it seems like a effort to allow Zidane's exit from the sport to seem a little less shameful by suggesting that Zidane's absurd attack was, while unfortunate, an "understandable" manly response to intolerable "provocation", crediting Zidane's ridiculous attempt to paint it as a matter of honor or principle.
