All Blacks assistant coach Leon MacDonald hinted there would be opportunities for new players in the American match. If Proctor gets the call, it would be a Test debut for the standout player for the Hurricanes this year.
Proctor said that having been with the side since the squad announcement, he had been soaking up the environment and absorbing information about the team's structures.
When the opportunity comes, I'll be ready. I am excited when the opportunity does come."
It is an intense environment, and there is pressure to be focused a lot of the time.
Proctor said having such an intense series against England in which to experience All Blacks rugby had been invaluable.
"England's a top nation in terms of rugby so, to be a part of those first couple of games and to witness how the boys went through their prep was cool, and a good start to being in the All Blacks' camp."
There were lessons he could apply for himself from the experience.
"That included how hard it is to beat a line-speed team, a team that can put you under a lot of pressure and a team that likes to kick the ball and put pressure on in a different way compared to the New Zealand-type of footy that we like to play."
Wing Caleb Clarke said he was hungry to get on the park, and missing selection for the England Tests ensured more fuel was in his tank to do well.
"There is a lot to play for and hopelly we'll get a chance to run against someone new."
There was competition among the team's three-quarters, but they were also helping each other.
"We're making sure each of us are putting our best foot forward as well. That's the best part about it, we're all so close in terms of who can wear the jersey. It's one of those frenemies vibes, but we all love each other, so that's good."
Blues teammate Mark Tele'a and Crusader Sevu Reece had been preferred for the first two Tests on the wings.
"That puts a lot of pressure on me to perform and put my best foot forward.
"It's great to see him [Tele'a] do his thing and it is just as important for Billy and myself to make sure we prepare the boys. It's putting a standard we all have to reach and we're looking forward to this challenge."
Both Proctor and Clarke emerged from their Super Rugby Pacific campaigns nursing rib injuries.
Clarke said, "The first week was a crack-up because Billy did the same thing, popping a rib cartilage. He had a week more to recover but at the first camp he'd look at me running and said, 'I know how you feel.' But we're back to 100 per cent and hopefully looking forward to running out there."
