sounds tragic, what is more important than havingthe right person for the game?

lol...reversely, i have problems playing inthe cold since i originate form a warm country.

I used to suffer quite severely in hot weather, but joined a gym where the air conditioning was not always working. This meant that aerobic spinning (cycling) sessions often took place during the summer in extremely hot conditions. I found that after a period of time doing this, that when I had to play hockey matches in heat I found my body much more able to cope. Perhaps the player mentioned should try jogging on hot days in the summer, for short period of time initially, I think his body would acclimatise slowly and he would find himself more able to cope for the odd hot game.

does the players have a naturally low blood pressure?
