"I think everyone's hungry," said Johnson, who is captaining the Warriors for the tournament. "No one's carrying anyone. Everyone's working, everyone's contributing, so that's the pleasing thing, especially about that last performance there. That was our whole team defence and you could see that the team stood up.
"No one came into this comp knowing what was going to happen and it's been that the best team that adapts on the run can often win. We've done that today, kept an open mind and like I said our big boys stood up in defence and got us that go forward to start our sets as well."
The Eels also emerged with a perfect winning record, beating the Roosters (18-11) and the Bulldogs (23-6), which was totally unexpected given they were one of the favourites before the tournament for the wooden spoon.
The Panthers were the only other team to win both games, beating an under-strength Storm 14-11 and then an ordinary Dragons outfit 23-8.
As predicted, Blue Pool is the most competitive and all four teams - Knights, Sharks, Titans, Tigers - ended the day with a one win, one loss record. The top two teams from the four pools progress to the quarter-finals, when it will be knockout football.
The tournament has been a success so far on and off the field and there were no reports of any major off-field incidents.
One of the biggest cheers of the day was reserved for 42-year-old Brad Fittler, who collected an intercept against the Broncos from 60m out and managed to hold off the cover defence to score.
