I agree that we should start to see some more creative players at 13, and JOC (James O'Connor) is certainly one of the options. I personally spruiked for Giteau being moved to 13 a year or so ago.
A big basher 12 with a light footed 13 could be interesting.
With Quade on the sideline for the next 6 months we have a different scenario developing in our 10/12/13 lineup.
Life outside quade has been like living in a shadow, the attacking focus tended to be either inside balls to 11 / 14 / 15 or to the forwards. Alternatively he used his big and accurate passing skills to go to the edges.
New No 10 bring a different perspective.
It comes down to the skills of the 10 plus the coaches opinion on what he can do and wants to do with those skills.
Personally I would love to see the coach look to have the centres perform a more attack oriented gameplan with lots of set piece moves, I find it very entertaining football to watch. For attack purposes I would be very interested in seeing all of JOC (James O'Connor), Horne, Tapuai, AAC (Adam Ashley-Cooper), play in the midfield. But not if they get the old 'play whats infront of you' plan. I'm not a fan.
N.B. I didn't like the programming that Eddie Jones put into place for the backs either, maybe more of a middle ground approach.
