Quote: JB Down Under "Scott Quinell
Jonathon Davies
I am pretty sure there are plenty of half backs who could make great RL players, likewise forwards, fullbacks, centres, wingers. Only position they probably don't have is hooker.'"
Jonathan Davies was a RU half back who played wing and centre in RL - Quinell struggled to get in a Wigan side.
In RL you need half backs to break the line and create things - that is the last thing you want in RU as you would lose the ball.
RL is a territorial game - RU is about keeping the ball the only thing they have in common is the shape of the ball and the first name. Centres and wingers play a similar game in attack but it is the defence where RU players would struggle.
