Quote: FearTheVee " My worry would not be tomkins ability to play there, but his ability to defend in the line.'"
Having seen Matty Smith's defence for a few years, I would say there's no weakening of the defensive line.
That said, with Graham and O'Loughlin do we really need a ball handling fullback? Too many chiefs and not enough Indians. Given Matty Smith's kicking is hit and miss and the more natural attacking game of Tomkins, I would move the latter in to the halves and take the former our of the team. Smith has proven himself effective in SL, especially with Wigan protecting him in the defensive line, but his all round game isn't strong enough/consistent enough for international RL.
As for moving players out of their club positions, where did jared Hayne play for Australia in the World Cup final and where did he play for the eels?
