Rugby doesn't have much time for the flawed character. No one cheers for a guy like Zac Guildford.
Other sports aren't so picky or so judgmental. The NFL is full of cult hero madmen. Some of their most idolised are now behind bars or lucky not to be. English football celebrates all sorts of odd balls. It's almost a case of the more dysfunctional, the better.
Paul Gascoigne wasn't so different to Guildford in that he too spent his career battling alcoholism. Gascoigne was never out of the papers in his prime. He did any number of daft things -- set fire to teammates' clothes, mouthed obscenities in broadcast promotions and wandered into the Middlesbrough canteen naked to order lunch and yet he was much loved and cherished. England didn't care that he was riddled with issues. Fans, coaches ... everyone wanted him to succeed.
And there were plenty of others just like him. Sporting heroes don't fit just the one mould.
Except in New Zealand rugby, where it seems there's an expectation that heroes have to be near perfect. Richie McCaw has signed off as the greatest player in All Black history. He hasn't put a foot wrong and shown this relentless capacity to do the right thing. Daniel Carter is much the same. Good, clean living country boys, they will be viewed for eternity as the perfect All Blacks. Held up as an example to all.
