I agree with what you're saying, but the problem i've found is that Hayne hasn't been given quality ball or no ball, so when he only gets the ball a couple of times in a game, he gets frustrated and tries too hard resulting in errors or runing around going no where.
And that's the whole problem. We don't know how to use our backs. It's been like that for years but at least Mateo tries to get it out there to INU and Hayne.
If those 2 passes were not called forward and Hayne or Inu scored off both, we would be saying he was great in the Centres.
But alas, it wasn't the case.
If we use him like the Drags use Gasnier (in which he roams sometimes to the other side of the field) then we would make better use of him.
It will take him a while to get use to the centres but couldn't we find a good ex-centre to speeden up the process?
I reckon get the ol' crow to teach him a few of the foundation old school stuff and then some recent retiree to teach him the modern game.
I don't see any point in putting him on the wing as we want to make him grow in a more important role and that's either centre or Fullback.
