no, the fact that you "own Aussies" are slamming him speaks bad of australia in general
I don't think it's the public so much as it is Tennis Australia, and every past male player - some of whom have been passed by Tomic in the way of achievements already.
Everyone - Masur, Rasheed, Rafter, Newcombe, Stolle - the boys club - want every junior to be the next Hewitt. Just a dogged fighter than never gives up on any point or any ball. Tomic is the exact opposite of that unfortunately and therefore they're all pressed
Let's not get carried away. It's not really up to anyone to decide if he deserves to compete or not. If we went down that road you could easily kick out half the players. Get's his ranking makes the main draw, that all that matters in that regard. He nor any player is in a popularity contest to decide if he should be allowed in or not.
That said, it's very clear Aussies were embarrassed by him on the world stage and hence the anger. You really shouldn't worry so much about that. No one outside Australia even knows the kid anyway.
We're not embarrassed by him at all. We're embarrassed about the entire landscape of Australian tennis. To think Tomic can save tennis single handedly is just not common sense.
They say that we need him at the top of the game to encourage an entire generation to take up tennis and in 10 years we'll have depth of talent and numbers at the top of the game. Well, 15 years ago we had Pat Rafter, Lleyton Hewitt and Mark Phillipoussis all winning slams or making finals/semis pretty consistently - and from that it looks like the only guy who was encouraged was Tomic
The Tennis Australia boys don't ever talk about the failures of every past promising junior (Reid, Klein, Guccione - who gets to travel as Lleytons side kick all year round on Tennis Australias back, etc) but they're very quick to get on Tomic. I don't even like the kid, but to put an entire nations standing in the game on one kid is ludicrous. They're just idiots.
And no, I don't think publicly berating him is going to motivate him.
I'm sure his dad isn't even telling him he played well when he goes down in straight sets with a bagel to Roddick. He'll get sick of losing all the time and getting no glory soon, and he'll get his ass into gear. If he doesn't, well obviously he's content with being a journeyman. That's up to him, it's his life - Tennis Australia didn't buy any right to it when they invested in him.
