Samoa are just one of those teams you don't want to face. They might not win, but they will wear you down and tire you out and inflict losses on your players because of their style. The perfect example of a team that dig in and hit hard. I remember in the last World Cup when England played them. I went down to my old Rugby club to watch the match and it was brutality - absolute brutality.
On a side note - a young MFB after a particularly muddy match. Not in my team's strip, but anothers'. We'd made a composite team for a fun match whilst on tour. Ah to be that thin again.
