"I feel like I've done the hard work to give myself all the confidence that I can just go in there and play my normal game."
Coach Andrew McFadden's 18-man squad includes senior forwards Jacob Lillyman, Ben Matulino, and Ryan Hoffman, while rookie front-rowers Albert Vete, Sam Lisone and Charlie Gubb round out their forward stocks.
Dynamic centres Konrad Hurrell and Solomone Kata and Kiwis rookie Tui Lolohea are among the outside backs, together with David Fusitu'a, Jonathan Wright, and Ken Maumalo, while 18-year-old playmaker Ata Hingano will be on debut.
McFadden is excited to be able to include Johnson and is confident there is no undue risk in fielding his key playmaker.
"It's no more risk than what we do at training so I'm pretty happy for him to play," said McFadden.
"He's fit and he's ready to go and there's no more risk than usual."
The absence of Kiwis co-captain Issac Luke should reassure Warriors fans that the club is erring on the side of caution with their player's health, with McFadden unwilling to risk the crafty No9 in the preseason tournament.
"We wanted Issac to play but he's had a couple of mishaps in the last five weeks, a couple of tight niggles, so we just said it's not worth risking," he said.
"Nothing too major but he's had a couple of little niggles that we just don't want to compromise at the start of our season."
The Warriors have thrilled spectators but fallen short of success in the last two nines tournaments (they were beaten semifinalists in 2014 and quarterfinalists last year) and have been dealt a tough draw this year with the Bulldogs, Sea Eagles and Broncos their opponents in the Hunua pool group.
And while there are huge expectations on them to hit the ground running from the start of the NRL season, McFadden insists he is taking a relaxed approach towards the Nines.
"Although we want to do well it's not going to make or break our season. We're still very focussed on the NRL season but we want to do well.
"There's really only expectation on us so we'll try to have some fun and take as much of that pressure off the players and enjoy the tournament."
