It was the off-season from hell. Fifita got locked up in Bali, Perese got his contract torn up, Bird, Lodge, Palasia, O'Sullivan, Glenn all suffered major injuries and the Broncos trial form was bad with the only win coming up against the Capras when they were at their worst. They couldn't even beat the Seagulls that year.
After their record loss, the Broncos made bugger all changes to the 17 when they took on the Cowboys. However the Cowboys were attrocious that night and allowed Brisbane to pull off a huge upset. Then COVID hit, the NRL tried to keep the lights on but the whole thing was called off after another upset against the Rabbits.
Maybe the opening two wins would have carried them over to the Titans game and they could have gone 3-0 and had more confidence. However depth was already a major issue and it wasn't shocking at all when they came up against the good teams like the Eels and Roosters that they got absolutely smashed.
