NSW utility Craig Wing claims his Origin III preparation will begin about 8pm on Wednesday night.

Forget the Blues' week-long camp on the NSW central coast or days of intense training and video analysis up in Brisbane, Wing says he will wait until kick-off in the Origin series finale to work out his method of attack.

"I try not to go into the game with too much of a game plan," Wing revealed.

"It's more once the game starts I start watching the players around the middle and start watching individuals and just before I go on I work out when I want to go and see what we're after."

According to Wing, the late preparation is part and parcel of being the bench utility.

In game one in Melbourne, Wing wasn't used until midway through the second half, but such was his impact in lifting NSW back into the game that he was slated for extra minutes in game two in Sydney.

Wing however was a late withdrawal from that match due to a hamstring injury, and admits the plan may have changed a little with the selection of Michael Ennis as NSW hooker for game three.

Ennis was selected as much for his terrific form as his combination with Bulldogs and NSW halfback Brett Kimmorley, and their combination could make it difficult to fit Wing into the mix.

"It's hard - with the other players and the forwards it's easy to interchange them because it's a set time thing and that's generally what happens in club footy," Wing said.

"The tough part with me is that I'm replacing guys that play 80 minutes every week.

"It's just a matter of when the coach feels it's the right time in the game - it's important for me not to get too excited too early but not to be too casual ... I just play it by ear I guess."

No matter when he gets on the field, Wing is just grateful to be given another shot at Origin football, especially after sitting in the coaches' box alongside the less than mild-mannered Blues coach Craig Bellamy in game two.

Wing says the experience all but extinguished any desire he may have ever had to coach a rugby league team, while it also ensured there would be no slackening off on Wednesday night.

"It gave me a bit of an insight into how he sees things and he's certainly very thorough - he doesn't miss anything at all," Wing said.

"Whether it's picked up on the video or not, you know he's picked it up ... there's no room to rest."
