Quote: Sal Paradise "That means he has to play every week and how you get transition with the inclusion of such an iconic and dominant individual playing I am not sure. He is certainly worth his place before Burrow, Achurch etc'"
I'd see him playing in a similar way to how Buderus and Burrow operated at the end of 2011.
When Burrow came off the bench, it was often not to replace Buderus but with the Australian shifting into a loose-forward role defending in the middle unit.
I reckon you could start Sinfield at 9, then bring Aiton off the bench say after 20 minutes and have Sinfield operate in a similar way to how Buderus did. A few carries, but not as a pivot and defending in the middle third. Also means you've got him out there for his kicking game.
He can then take a breather at some point in the game if he needs to with one of the other back row options slotting in to that middle unit and doing a similar job.
