Actually when think about it, reaching 3 finals in a row is really impressive. If we compare:
Earlier this year, LD played German, All England and Swiss in a row, he didn't finish, got injured (partly due to fatigue should be a reasonable guess) in Swiss SF. LCW played one local tournament, Japan and Chinese Taipei in a row, got beaten by Simon Santoso in QF of the last one.
So TH's stamina should be OK. What is not OK is that his smashes are much much weaker than even last year, when he can constantly smash 290-300km/h (in 06 WC).
