Now it's almost impossible to argue that Dan Carter is not the most dominant fly half in the world right, but this is most arguably his last world cup and he will no doubt start to fade in the coming years. Which brings me to the point of whose will take Carter's reign in world rugby? From the south, most would find Quade Cooper a worthy successor, but I find his kicking a little lacking. From the north Toby Flood looked poised to take a stab at developing exponential potential, but outside of test rugby, he has been average at best. My bet for the next dominant force in rugby is Ireland's Johnny Sexton; as his kicking is superb and his poise on the field is no doubt world class. Let me know what you think.
