Totally agree with this. Sometimes the crowd will even switch from the favorite to the underdog, just to keep things going. (Classic example: FO 2004 final, crowd tried to bolster Gaudio who was losing badly, he let it buoy him, and Coria let it destroy him.) Djokovic wants it both ways. He wants the love, but when he's not getting it, he lets the crowd know his displeasure, as he did today, by engaging a fan, and blowing the fake kiss at the end. He KNEW they weren't going to be on his side today. Why make it worse for yourself come Sunday?
