Even when they have an off day lately the AB still pull out a win. What's needed for the underdog team is not to be intimidated by the fact that they are playing the best team in rugby so that they can actually recognize when the AB are having an off game, and then take advantage of it.
All joking aside, it sounds like Scotland is working on their team morale. Instead of accepting that they're going to lose, they're convincing themselves that they have the ability to win. Player mindset can have a strong bearing on how well (or poorly) a team plays, and on the outcome of the game. And you never know, while the ABs are laughing at Scotland's boasts they just might get caught with their shorts down in a thistle patch.
Yeah, yeah...I know...fat chance. But even though the ABs are *my* team, my Scottish blood can't help but root for the boys in blue.
