Crusaders assistant forward's coach Jason Ryan is determined to improve the scrums for this weekend's game against the New South Wales Waratahs.
The scrum is usually a potent weapon for the team, but caused frustration and injury against the Force at AMI stadium on Friday.
"The scrums were disappointing, and no one wants to see that in the game. The spectators don't, the players don't and neither does the ref," Ryan said.
He compared the team's scrum to a mixed-up rowing eight.
"A few boys got their oars out of the water... We had four oars out of the water and were going around in circles."
The Crusaders play the Waratahs in Sydney on Sunday at 6.05pm (NZ time) .
