Minnows at the Rugby World Cup

What is the point of giving yellow cards out to the Portuguese for technical offences against Scotland. Surely you need to keep the game as balanced as possible - fine give out cards for violent offences and dangerous play but make every effort to keep it to 15 against 14. The Portuguese have only 2 professional players for goodness' sake - they are certainly never going to beat the Scots, but they deserve to be given every opportunity to show what they can do. Putting on 100 points against a lesser nation does no-one any god, not the wining side as they don't get anythying from a thrashing, not the minnows, not the crowd, not the TV audience.

Superb first half try by the Portuguese by the way. If Leal is not playing professionally somewhere after this WC, I'm no judge of rugby.
