I really just can’t agree with this.
No doubt Hayne had a purple patch where he was almost unstoppable, but one, one and a bit standout seasons does not make you an all-time great.
If he sustained that form the entire time, absolutely. But based on his career form before even going to the NFL (9 seasons); does he really belong in the conversation with the greats from only his own generation like Lockyer, Smith, Thurston and Slater and Inglis to a lesser degree?
I really don’t think so.
EDIT: he was a lot like purple-patch Barba in that, in isolating their amazing runs, they were phenomenal. But when you look more broadly at their careers, they were good, but also floated in and out of games, as well as form, quite a bit.
Greats don’t do that.
