You Kiwi's can say what you want but Cruden is not 2nd best pivot in the world. Not by a long way. That is all in you heads. Hell, in your heads Barrett is 3rd, Noakes is 4th, Slade is 5th. You guys have the best 5 players in the world in each position dont you? You guys produce top rugby quality in the world all round...If only you could do the same with your refs now.
Cruden has a lot more proving to do until you can make that statement. Cruden would not be considered for a world team at present. Carter is leagues above Cruden. Cruden's defence is also up to shit most of the time. He gives away easy metres in the hit. He option taking is nowhere near that of Carter. His goal kicking is hit and miss.
Toomua in terms of all round ability is much better. He has all the skills Cruden does and is a brilliant defender. Lealifano doesn't even need to play 10 and we know he is better. He has proven that already. I dont have to say anyone from SA is better because we do not possess a great flyhalf at the moment but I will tell you that Cruden is not 2nd best in the world. Thats in your head.
The northern hemisphere will tell you their comps are harder, the Southern will tell you theirs are. Their is no bigger stage than the International stage and Cruden has not achieved even 5% of what Dan Carter has. Cruden may as well link up with Wynand Olivier and have a chat. Wynand was year in and year out, hands down the best 12 in the comp. Thats why Bulls were so dominant in that era but put a green and gold jersey on him and he couldn't do shit. Much like Cruden. The step up is a little greater than them right now. They are loose players and can get away with it is Super rugby. International is a lot tighter and mistakes much more costly to which Cruden still makes many and takes many more ridiculous options that Dan wouldn't. Thats what makes Dan so good. His ability to adapt between the two. Some guys have it, some dont and thats why we have legends of the game and rank run of the millers.
Maybe when Carter is out of the picture and Cruden can relax in the knowledge that he owns the jersey as long as he puts in the work needed he can come into his own (Same with Wynand always knowing he was a fill in for Jean or Jacque) but until then, he is not 2nd best in the world.
