If the Sharks would "happily assist in making it happen", that says to me that their attitude to Shaun Johnson is "no great loss." Without re-hashing the Pro-Shaun Johnson v Anti-Shaun Johnson stuff too much, do we really want to invest in a player his current club are - if I read your comment correctly, I accept your "happily assist" might mean a player swap, which is much more a "we'll miss ya Shaun Johnson, but we miss not having a good fullback more!" type situation - meh about keeping?
I don't think it's fair to move on PH and Chanel Harris-Tavita - unless they've had offers - as, frankly, we've not seen enough. KN's going to be hooker going forward - hopefully doing that on the field too! - as I still think we're stuck with Egan/Lawton in that department, even allowing for the massive probability that Roache will have a longer time to get himself ready for a return to rugby league that might not end well. So if Green goes, yes we need a senior half to help Chanel Harris-Tavita/AK.
Forwards - I think we need a hard, mean outta-my-way type. Our forward momentum seems to be "Oh, you got a hand on me! Ya got me, cobber!" passive. I mean a James Graham-type. Maybe we already have one or two of those, but have we seen signs of that?
Number one wish for 2021 is Iro leaving. He's had all these years to make a difference and what difference has he made - in whatever role he's had? Maybe he's promoted to ouside/beyond his ability - which I suspect Ackland may have been. Jones/Brown/Morgan - maybe one of those gets a new role in 2021 and we replace them with an outsider. Obviously, if Kearney is given the Thank You Mooks Now Sod Off talk - or he finally realises he freaking hates living away from his family and I know I couldn't do it - obviously his replacement needs to be 2021's Number One Biggest Signing.
