How about this deal? (Assuming we cannot get Grant or C Smith for 2021)
2021 - Offer Bird to Dragons in direct swap with Ben Hunt. Broncos to pay excess of Hunt's 1.2 mill salary (say $250K). Bird gets his release, Dragons get Bird and save a couple of hundred grand for next season. We are out of pocket about $250K on top of what we would have paid for Bird next year but it solves a fairly decent hole in our squad.
2022 & 2023 - Hunt's large contract now becomes our problem but Dragon's could and should be convinced to pay $250k per season for the remaining length of that ridiculous contract which means our financial commitment to Hunt would be around $950k per year for 2 years. By then we may have moved on from Milford or potentially reduced his contract. In Hunt we get a tough, experienced, representative, 80 minute hooker with a kicking game. He is also a ready-made half should we need coverage. He also has Broncos in his blood. Dragons then have around a million a year freed up to re-sign a resurgent Bird or someone else. I reckon that's not a bad deal for both clubs.
