From what I've been told with CJ the Knights' offer was only marginally less than what Cronulla offered, and all things equal probably would've been the smarter decision with the difference in cost of living (though I'd say she's probably not paying rent which negates that to some extent). Knights played chicken and she called their bluff, and then wouldn't budge after verbally agreeing with Cronulla when the Knights tried to salvage things with a bigger offer. She also then proceeded to get a season-ending injuring during training which became something the squad as a whole had an issue with, saying Jeffries was overworking them.
Based on those things I doubt she's overly keen to come back so soon, but the major life changes since then would probably help our chances.
