I've been in situations where I just wanted out ... mind you I wasn't making $1mm ...
In one case my employer was okay moving me, in another case I just wanted an adventure out of the country, and the last case I wanted away from an employer who wanted to keep me, asked me to stay that they'd work with my wants.
I took my own initiative on 2 cases where I cut the safety net and moved on.
Have to say Robertson could do the same. Be brave and go overseas and earn some money, might be less, but that is likely a better option than just refusing to sign and therefore putting himself on the bench.
He could easily get a job overseas. Or at least I think he could. He's a good young player.
