Damir and Mrs Cloke? 
They would be the closest the AFL has to a Tomic/Hewitt scenario. Perhaps I should have inserted the word the "majority of parents"
But I don't think I ever heard the Clokes tell their sons to leave the field because an umpiring decsion has gone against them; like Tomic's father did early this year in Perth I think it was.
I don't see Damir heading onto Gosch's Paddock or Visy Park and training his sons seperately to the the rest of their team mates. There is a very interesting article in one of the papers about how Woodbridge (Aust Davis Cup) has had to tread very softly with dealing with Tomic as to not to upset his father, it is very similar to what used to happen to Phillouposis (sp?) years ago
I don't see the Clokes travelling all around the country side every time their sons play interstate - like the Hewitts do with Lleyton.
Do we see them at games yeah we do
Should Damir Cloke be managing his sons - no he shouldn't and yes some of his comments over the years have been cringe worthy and have made him and his family look like fools (hence why he's nickenamed Damir)
But I still think there is a massive difference between comparing football parents to the extreme cases in tennis in this case the Hewitt/Tomic models
