I used those examples as they are two of the obvious ones. But:
some wingers offer speed: JAC, AKP, Coates, Savage, Saab.
Some offer a kick target: Lomax, Coates, Tupou, Warbrick, Bostock.
Some offer tackle breaks and running metres: Lomax, To'o, Marzhew, Kiraz, Tamale.
I don't see anything special that Turuva offers. You cited work rate but the stats don't really support that. His work rate is solid and better than average but hardly anything special.
Having said all that, I don't by any means think he is a bad player at all, as I said a little above average. More than happy for him to be on a wing. I just don't agree with the hype he receives on here with the original comment I responded to being one of many that has said something along the lines of one of the best in the comp.
