You two are right. Actually I'm a little angry with how Roger was performing there. To lower my hope, he should at least push the match to the 3rd set. I can't bear him losing to JC or someone else like Andy, who are his main opponents in quite some years, even if I know clearly it was just an exhibition. But his loss would boost JC(or someone else)'s confidence. It's absolutely not helpful in bigger occasions.
I think it's his characteristic that decides his attitude and performance. Maybe it's right or even good not to take everything serious. So let's be tolerant. And like you, I also think in AO it'll be totally a different story.
I just posted some of my Miami pics (from 2002 believe it or not) at the Shirtless thread in General Messages. There are three of Rogi, very nice pics. Found them this morning when I was searching amongst my archived pics...if you want them here, let me know by PM or otherwise and I'd be happy to post them.
