Barritt, Burrell, Eastmond, Tompkins, Tuilagi, Twelvetrees have played 12/13 in the past year. On top of that they've used Flood/Farrell as 2nd 5/8th. It appears Barritt and Tompkins are out and I wouldn't be at all jealous of having them 2 as options. The only player who appears to be nailed on is Tuilagi so much so that he started at wing last Saturday. Granted a lot of those selections were to some extent injury enforced but that's still a high number of different combinations. Whether it's brave or not to experiment with so many combinations or pick one and let it bed in is debatable. It seemed to work at fullback and scrumhalf. I kind of like it but not Tuilagi on the wing.
Was impressed by Burrell in the 6N and what I've seen of him for saints would be interested to see him and Tuilagi in the middle. For that to work though I think they need a more creative OH. Twelvetress consistently does some good things and some bad things and again I wouldn't be jealous of him as an option. While it's good to see them trying to add a string to their bow I don't think it's a foregone conclusion that they will. IMO by the end of next years 6n he'll have to have settled on a combination whatever it's limitations. As you say.
Essentially I think they need to do a Gatland on it. I can understand why they would want to vary their game (and they can do it in other ways than having an all dancing midfield) but if they just copy Wales a bit, it'd be better to get 100% competent at what they're good at than to diminish their midfield power by forcing non-footballers to play ball or having lesser players step in and decreasing the impact of someone like Tuilagi.
I'm not convinced it will be enough though. There inability to convert dominance into scores cost them the 6N and was also costly against NZ.
On Farrell, he is undisputed first choice 10. He hasn't developed enough this season or last. Even at club level(Barritt/Tompkins midfield) when Saracens need trys they look to Charlie Hodgson. I can't see him developing that much in a year for the RWC.(He's starting to break with increased frequency as well). His competition for the jersey is no healthier than Sextons and just as green too. Burns was only in the squad because Ford (less than 5 caps ) got injured. Though he showed up well in the first test after a bad season at Gloucester(there's hope for Madigan) he was dropped as soon as Farrell was available. if they're sticking with Farrell at 10 they've got a problem in Midfield
Ruddock's tackle stats consistently too low for me to be taken seriously as a Six Nations blindside..... Ruddock's defensive stats don't stack up. - All Blacks Nil, Jan 15th, 2014
