premise: Better than it is on TV . The stadium is pretty small and so steep , so you still get to see everything , and they show the TV coverage on the screens in the stadium . Oh , oh , and I think I saw Roger Federer ! After the Serena / Safina match was over , two guys came on the court and started practicing , and one of them was wearing a jacket and cap , but he totally had Federer 's hair . We asked a usher who he was , but he said they were junior players . What 's a possible reason it 's better in the stadium than on TV ?
hypothesis: Because it 's live and the fans can be part of the atmosphere .
