Jase...There are always individuals with that something extra. I know from my own experience at playing at a decent amateur level,that the conditioning and power of the modern rugby league forward makes them a formidable opponent.
Hell I remember us having an Aussie and a Kiwi play for us for a couple of months,(they were over trying to win contracts with Chorley at the time) I could always match up to the biggest of guys I played against, but these two made you wince every time they tackled someone....and they were struggling to get started with a lowly pro side at the time.
