Naden just flat out refuses to pass, that’s a huge problem in itself. His defence & lack of passing to his outside man makes him a winger in my view.
I take your point that Blake also had technical deficiencies, but I genuinely think Naden’s are worse. His instincts in chasing kicks & taking the high ball are however very good, and could easily be used on the wing.
I’m not really trying prove one or the other has bigger deficiencies my main point is Blake, who clearly had done deficiencies was still able to take big steps over his time here and become a very good player. There is no reason Naden won’t take a big step this year and improve his defence or become a better passer. The fact he is doing his first preseason with a full time nrl contract might give him more room for improvement.
Naden probably is better suited to the wing, I’ve said not long ago I’d put Naden on the wing and Too in the centres, both players should benefit.
