Because Olakau’atu plays second row, not lock.Therein lies the problem LC. 'Its a fact'. Based on whose opinion? Why does Olokau'atu play wide then. He scores several of his tries out near the centres, and he's obviously trained that way to use DCE's kicking and the 5/8s getting the ball out to him. Schuster as a second rower usually played outside Foran in attack in 2021. He might play closer in defense, but in attack he ranges wide often. Menzies did the same thing. And again you are expressing an opinion. There are no absolutes my friend, only perspectives and everyone of us has a different one.
There are absolutes, you’re just choosing to ignore them.
Lock is not 2nd row in the modern game. Locks play in the middle of the field.
