HITTING the ground running, the Blues opening Origin training session in Coffs Harbour today focussed on combinations, set pieces and team bonding.

With seven changes to the NSW side following last year's series, the Bulldogs rookie halves combination of Josh Reynolds and Trent Hodkinson looked to find rhythm behind an established forward pack.

The opening ball work session at the Novotel Pacific Bay Resort training centre was followed by the official team photograph.

One player whose loving the Bulldogs feel to the team is Josh Morris, who will rely on quality ball from his teammates in the halves.

"They add that enthusiasm and bring their form to the team leading into Origin I," Morris said.

"When your team is going well those kind of rewards fall into place, so I guess it's a big thank you to our teammates for getting us here."

Fellow Bulldogs teammate Tony Williams played a major ball running role in the session and could prove a game changing strike weapon close to the Maroons' line.

"T-Rex has been outstanding for the Bulldogs and obviously with Frank (Pritchard) getting injured he has moved over to the left hand side and is playing 80 minutes something he probably wasn't doing last year," Morris said.

"I think he's getting out there and running hard making people wary of him."

With the Bulldogs meeting the Roosters on Friday night in the NRL, the Dogs Origin players will watch on in the company of Roosters representatives Michael Jennings and Daniel Tupou.

As for the obvious question to Morris, how he will stop Greg Inglis, the centre shared a laugh.

"In my eyes (Inglis) is still the best centre in the world, he is a very dangerous player and I look forward to every time I go out and play him, he's a hard man to contain and I'll do my best."

"You have just got to get as close as possible and try not to get fended in the face and made to look like a fool."
