Wrong and wrong, sorry.
The Tigers didn't play in hot or humid weather, they were terrible and outplayed. They didn't tire but kicked into a huge wind in the last. In the 3rd, they should have destroyed the Suns, but messed about with the ball and missed their opportunities. I live up near Cairns and the Tigers couldn't have asked for better weather. You make a fair point about the effects of the humidity, just using the Tigers as an example is an understandable, but wrong example.
I also think it's wrong to say next week will show where we are. Few (if any) teams have won after playing in Darwin. The humidity is stifling, players lose a hell of a lot of fluids and they generally play flat the next week. I reckon we'll get belted next week, but it won't tell me much as history tells me that's what to expect.
