i totally agree. i've been saying for years that mcguire at leeds could be be a world class full back. i'm all for players learning new skills/positions, chris bridge at our place has played almost every position apart from prop.
with tomkins the potential is there, greater than myler/eastmond to become a genuine world class half back. it's wigan's choice to try and turn him into billy slater mk2, in sl that will probably work, especially in a team that bosses most of it's games. in the international arena, i'm not so sure, plus who replaces him at so..? don't say pryce!
