It's like arguing about how long is a piece of string, does this mean that Ben Henry can sue because he had career ending injuries? Chase Stanley?Jharal Yow Yeh? These players get the best medical treatment money can buy, you try getting in for a scan in the time these guys do almost impossible. You have former legends of the game now almost crippled not through one injury but a career of broken this, torn that, ruptured it again, fuck it give me a shot the team needs me I'll play through it.
And for a lot of players this is it there is no fullback option, all the eggs are in one basket league star or bust. And in the end I don't think this is about Alex suing the NRL this is about his insurance company balking at meeting it's responsibilities and trying to share the burden.
