The experience would be amazing BUT this team needs strong defenders from 1-17 before even thinking about attack. I like him as an option but I think the cons outweigh the pros...
For me, factoring in value for money I'd be looking at Capewell (although his cost may have went up after origin unfortunately), asiata (not a massive fan but I can appreciate that they are trying to give us more diversity in the middle and he's a strong defender), drinkwater (I'd take him over Allen by a long margin, but he's more likely if we target 2022 with a hope for an early release), Elijah Taylor (cheap, strong defemder, bit of ball playing, experienced), Copley (depth, cheap, good attitude)...
Id also chuck in gagai if a decent chunk of his wage got paid (possibility due to souffs cap troubles, although Roberts sacrificing***** his contract frees up their cash *cough nothing suss AGAIN for souffs NRL cough*.. I know he doesn't play AS WELL at club level but he is turning into a bit of a QLD legend, someone that the young guys might look up to and he might turn in some stronger performances playing in the Broncos jersey at Suncorp anyway), and grant is a pipe dream, won't happen (but I also think turpin is NOT A BAD OPTION AT ALL, he hardly played last year and when he did he was obviously injured or not fully fit/recovering. He will run the ball more when he is fully fit).
If we got ALL of the above players I'd be willing to let go of Macca (great attitude and defence but 600,000 for a back up hooker with no impact off the bench... no), oates (he may recapture his form someday but I don't think it will be at the Broncos, seems to have a poor attitude), bird (gone already, would have liked to have kept him but not for the money he was on and not if we can get another player out of it, purely due to the risk of injury (he won't get one now for the rest of his career I bet lol)), ofa (see oates above). The above together with whatever we had set aside for fifita (we may have had 750 but no way we had nothing despite the media bs), and boyds retirement would allow us to buy the other players with some shrewd accounting. If it isn't, and only if we could get all of the above, I'd try get something for lodge. I like him and he will be great again, ppl forget how good he was for us and how much he helped haas, but he's on a bit of coin, may be wanted, and I think Walter's way of coaching could be helped by having more queenslanders in the team (Walter's will push identity and passion). Trheres no way of re-sign luke, teo I would.
Also, for re-signings, I'd prioritise dearden over staggs. Premiership teams are built around spine players, not highlight reel players. You need players like staggs to win them but you don't build the team around them.
We need to stop trying to sign superstars and think about value for money. The superstars haven't worked for us for literally decades. Develop the superstars, buy the solid and reliable first graders to help them develop...
