I agree with you. He is a very different player for Saracens than you see for England. For England he is often the facilitator. Not the playmaker or runner etc...just the one who continuously ensures the gameplan is on course. But often thats the issue....fine when its working...but when its going horribly wrong you have to change the gameplan.Part of my point is that no gameplan is so rigid that the 10 should ignore overlaps and good attacking opportunities simply because that's not what the next phase is supposed to look like.
Farrell is often described as a 'coach on the pitch' or 'the orchestrator of the attack' etc. I can see that with Saracens, but for England all he appears to do is follow a plan regardless of whether it's the right thing to do or not. If he really is running the show, he's doing a bad job of it.
Even if he is being asked to follow a 'robotic' game plan, he has the experience and ability to change it when opportunities come up, but he just doesn't … he's the captain FFS, it's not like he's going to be dropped for making good decisions on the fly.
I said above i firmly believe it will be Ford and Farrell 10 and 12...and i still believe it will be. and one of Lawrence or Manu at 13 for the oomph.
