The father of Sharks skipper Paul Gallen has slammed the Australian Sports Anti-doping Authority's pursuit of Cronulla players over the 2011 supplements program as "a joke", while coach Shane Flanagan says he would go through the whole ordeal again to savour an NRL title.

While there is a sense of the Sharks having finally put the dark days of 2014 behind them, the hurt still lingered in the dressing rooms hours after players held on for their maiden premiership on Sunday night.

Garry Gallen was scathing about the investigation that resulted in his son and a number of other Cronulla players accepting backdated "doped and duped" bans that amounted to three games on the sidelines

"They charged him and he had to take three weeks out of the game," Gallen senior said. "What a joke. ASADA knew they were wrong all along. You can print that, as far as I'm concerned."
