NRL premiers Cronulla have been slammed by coach Shane Flanagan (pictured) after Sunday afternoons 16 – 10 loss to the Dragons.

While there were some positives for the club, in particular those of Luke Lewis and Jack Bird, a lack of discipline was a major factor in the Sharks loss.

The loss of Wade Graham after repeated head knocks certainly didn’t help the premiers chances but the coach said no team could repeatedly be penalised while in possession and hope to have any real chance of victory.
