He's still working on his play selection and like most kids he will zig when he should zag on occasion.
Heck Caufield still does it and Suzuki to a lesser extent.
I can't see why anyone would doubt the skills though and some still do.
Passes like the one he fed Suzuki with on the PP and shots like the three recent goals he scored aren't skills that will suddenly disappear.
His production will increase with better play selection which will happen as the game slows down for him.
We've seen what he can do with time and space on the PP and it can't help but get better 5v5.
