Although i do believe you make a good point i dont fully agree. Mako and billy have to be starters as both of them have a workrate rivaled by non and have a very good fitness level for their workrate and size. 

The fast start being able to catch a team off guard and to get early scores has the goal.

Maybe drob 1 or 2 to the bench for the finisher role but i think trust has been an issue by EJ. he trusts Faz amd when his head drops and keeps him on, he trusts youngs even when robson would make a difference.  Although ford does have a few defensive issues he can control an attack better than faz, reigniting an attack, without ford leicester would have been relegated.

Also we need to see when our kicking game is being used against us which we dont seem to do. We just keep booting it down the field after we lose the advantage gained by the fast start, so if the tides turn against use then keep the ball and go through phases. And wait for the right time to kick(if it comes)

England have alot to sort but i don't believe its to late as the core is there.
