Throwing of objects of any kind is unacceptable at any sporting ground be it Parra stadium or Suncorp. It don't matter, fans shouldn't throw anything.
Secondly I think it's a bit harsh for people to think all Parra, Manly or Dogs supporters can stoop to those sorts of lows. There are always one or two idiots who ruin it for everyone else. Surely the Parra fans by now couldn't care less about what happened in 2004. If they do then they must hold a grudge for far too long.
Now, the whole subject of Lyon. Well, he's whinged about people throwing coins.
'Oh my god, my former clubs's fans are throwing coins at me and my team!' Geeze. Grow up mate. I would think the insults that were aimed at the Penrith players on Friday night were far more painful and hurtful for them then a bunch of 20c coins would be at Lyon. Geeze.
End result: Sea Eagles won, Lyon got the double so get over it. Those people who did the coin throwing- dumb cowadly act.
