Walker is not a bargain halfback now, let alone soon. He was poached from the Broncos and was a highly touted junior. I think because he got dropped last year, people assume he must be cheap but the Chooks paid good money to get him and his contract was upgraded when he burst onto the scene as the best young playmaker in the game 2-3 years ago.
He was shopped to the Dolphins just 12 months ago, well May last year and was told he was not wanted in June last year.
I'd suggest he is on around $400K.
Luckily for him he bounced back and will get good money after his current contract ends after 2025.
