Overreaction of the century.
I think you are overestimating what ten hours first class travel will do to the players.
They are top level athletes and are surrounded by sports science professionals. They will stay hydrated. Most of them will sleep on the return.
It's uncomparable to how most of us shit munchers have to travel, with our knees round our ears, surrounded by crying babies and a wedged in by a clinically obese Brummy who's packed his own egg sandwiches.
These are the games in front of us, we will win some, we will lose some.
Surely Poch has done enough by now for us to have faith in his and his staff's decisions, and for us to realise that they, not us, are best informed as to what the optimum strategy is to win as many games as possible.
Sorry i'll rephrase that for the target audience:
POCH KNOWS GOODER THAN EVERYBODY ELSE TO BE WIN BOTH GAMES.
