I also agree that Chan is more outspoken and could be more humble, but he was facing a lot of flack for something that was out of his hands. It must be hard being asked after you won "Did you deserve to win? Did the judges get it wrong?" when you're already disappointed in yourself and likely yourself questioning the legitimacy of your win. That comment about Ten not walking through the door was an arrogant statement though, seeing as how Denis really had the skate of his life and save for the flip tried his hardest to outskate Chan -- and he did by winning the FS, he just couldn't make up the SP gap.
I hate the general statement "left the door open and so-and-so walks right through it"... it almost debases a legitimate victory -- like "he only won because I made errors". And it's a stupid idiom because somebody could skate earlier or later than somebody else without really paying heed to what the other does. If Ten skated before Patrick then you can't say Patrick left the door open for him.
