The player knocked it past Tugay and caught his trailing foot, Tugay didn't mean it but there was contact and it was a penalty, we would have been screaming for it at the other end, never a sending off though. As for Zokora (I think it was) who went down, yes it was him making a meal of it, but didn't exactly change the game. I also think the Spurs sending off was harsh, though I wouldn't mind seeing it again.
I've watched the replay tons of times and wasn't sure, I can't see how we can expect the officials to be. Would have loved to have had it, but if he hadn't made a mistake for us then I wouldn't have complained about it too much, though we are owed a bit of luck.
