It depends
If we are seeing 2020 as another season of building and developing our own players, then we don't really need much of a turnover. Shed a few of the 'squad' type players (people like Ashley Gibson, Jon Magrin etc), promote younger players into those slots - and we should be set for middle to upper level of this division.
Or are we going to make a serious assault on promotion? With Toronto likely to be out of this division, quite probably replaced by London (who aren't going to be spending massively) then we could theoretically be in the mix to get promotion along with them, and probably Leigh, Widnes, Featherstone etc. We'll have more central funding than we had this season, and we've banked money from the Cup run this season - so, yeah, why not see about signing some real quality and giving it a go next year?
