Exactly my thoughts, he will go down in rankings maybe next year, but still need to learn on ATP level (see today).
And he won´t play Blava CH, he told me after DC that Paris will be his last tournie. I asked Kucera why, and he said that he will play it if he would fight for seeding at AO - then he won St. Petersburg and it was clear after then.
He'll have to pick his events. Does he play the South American events well Viña and Sao Paulo(indoor) are weaker than Buenos Aires and Acapulco or the Euro indoor events. They'll have a WC handy if he changes his mind.
Today was rare Seppi was so frustrated he normally doesn't throw the racquet. He has made the most out of his talents, even while he had his best ever Slam result, it's an area he needs to improve but very hard for him with the game and consistent level he is at. In the way, he'll fight hard and compete, but doesn't have that big weapon.
