It's difficult to say since 2024 was such an injury-plagued year for Bukowski. I'd dare say his 2023 was more impressive when he had less disruptions and got to play alongside Black. He's certainly worth persisting with, but he's well off NRL standard. Unless something happens with Paix, I'd be surprised if he plays any QCup this year.
Both Black and Mozer are very similar players to me. They both have a ton of class and they've been the stand-out players of their age group but I wouldn't make any Taumalolo esque long term commitments to either of them. When I watch Black I'm not seeing a young Nathan Cleary and Mozer isn't exactly setting the QCup alight like Grant was at the Falcons. So no, I wouldn't sell the farm to keep either at this stage but they're both highly rated at the club and there's little to suggest either are on the move.
Brisbane have a few alternatives coming through in Braithen Scott, Marley McLaren, Preston Cassidy, Sam Martin and Max Blanch. The Broncos always have quality prospects coming through the pipeline, they just need to track the progress and ensure they're keeping an eye on the market for those blue chip QCup/NSW Cup players who make a huge difference when it comes to balancing the roster.
