Surprising poll results, IMO.
The only advantage I see for Murray is the fact that he should be fresher (because of the day off and the fact that Djokovic played a five setter), but even that would be only an excuse for the Djokovic fans (in the end, he played 3 and a half hour, not a five-hour match).
On the other hand, Djokovic has won this title four times - Murray has yet to win his first and he's actually lost to Djokovic three times there (twice in the final). Murray's had his chances and haven't used them, why it would be different this time?
There is a reason why Djokovic won all those matches, this court simply suits his game more than any other, while Murray, even though he's had a great results here in the past, his flat groundstrokes simply don't penetrate through this court as they do on the faster ones (Queens/Wimbledon, Cincinnati, USO).
This reminds me of the Djokovic - Nadal matches at the French Open. People give Djokovic more chances every year, by totally ignoring the history and the fact that he's had five, four or six chances to beat Nadal, but he ends up losing every time. I believe it will be no different this time.
Anyway, may the best man win.
