Of course the Riders are going to try persuade him, but chances are basically nill that he signs there.
Put yourself in his shoes. A 3 year extension at around 600k per year is going to offered by Edmonton, BC, Sask, and maybe even Calgary throws their hat into the ring.
This very well could be his last contract if he wants it to be as he's not a spring chicken and he's made some decent money in his career.
Abandon the city he played most of his career in (Edmonton), pass up the chance to play in Vancouver closer to family, to play in a dump of a small town in Regina?
