NRL great Luke Keary has delivered a blunt assessment of the Canterbury Bulldogs spine, suggesting that the club are set for a significant shake-up at the end of the season.

Over the past two seasons, coach Cameron Ciraldo has made several changes to his spine in the ongoing search to not only find the right combination but also the right balance.

This has seen him sign Lachlan Galvin, let go of Toby Sexton and Reed Mahoney and rotate options across the four key positions of his spine, such as moving skipper Stephen Crichton from the centres and into the halves.

Ciraldo’s continual adjustment has seen Keary make a bold prediction about what he believes is coming next at the Bulldogs as they look to win their first premiership since 2004 in the next few years.

“We will see a new Bulldogs spine. I can guarantee you there will be a new nine, seven, six and one,” Keary said on NRL 360.

“Galvin will be the six. They need to find a seven. Whether it’s (Alex) Conti or (Mitchell) Woods or need to get one.

“I think Connor Tracey will move to maybe a 14 role. The whole thing will be turned over. (Freddy Lussick) will be their nine because they haven’t got one at the moment.”

Keary’s comments opened up the debate on the club’s decision to put Crichton in the halves last weekend against the Sea Eagles and revert Matt Burton back to the centres.

While the halves reshuffle caught the attention of many across the rugby league world, the decision paid off as they emerged victorious in golden point.

However, it only added to Keary’s point that Galvin is the only one to have locked in his spot in the spine with Crichton likely to drop back to the outside back either in the coming weeks or at season’s end.

“In my opinion, he’s not playing six, he’s playing seven,” Keary added on Crichton’s move to partner Galvin in the halves.

“He played halfback on the weekend. He ran the ball three times and did all the organising for them. He did all the kicking.

“He had 15 kicks to Galvin’s five and he didn’t run the ball. He played halfback.

“He was their number seven, and Galvin played as their number six. He is their best option at seven – the best organiser.

“Galvin is their long-term six so they need to find a seven.”
