Ali Williams has scoffed at suggestions the Blues and Crusaders are being hampered by a World Cup hangover.
Both teams are packed with All Blacks and yet are the worst performing New Zealand teams with one win from three matches. By contrast, the Highlanders have won all of their games, including an upset over the Crusaders in round two in which they fielded only three World Cup All Blacks - Andrew Hore, Adam Thomson and Hosea Gear.
The Chiefs have knocked over the Crusaders and Blues despite the apparent handicap of a "weak'' tight five, while the Hurricanes strung two wins together on the road against the Lions and Force.
Mention the hangover theory to Blues lock Williams, though, and it will be met with laughter and a shake of the head.
"It's a long season,'' he said. "You've got to build things up. People expect players to play at the best of their ability all the time, which is fair enough but in reality it's not going to happen. It's just one of those things - small errors that are in the game at the moment.''
