according to Slothfield ... although, i'm not sure how he came up with that, from watching that segment, it seemed like he was making a suggestion to the Knight, not necessarily something the Knights have considered at this stage.
I also don't think the Knights have as much money in their cap as Slothfield thinks ... they paid big money to Ponga and likely to Guerra, Pearce and decent coin to Moga and Ese'ese. they also bought Heighington, Lilyman, Griffin and Watson this season.
all up their recruitment for 2018 would have set them back sizable amount and I don't think any of them are 1 year contracts
