The versatile 31-year-old's punishing defence while playing five-eighth against Melbourne in the 30-14 win last week clearly inspired his teammates.
That team effort was the blueprint Walters said the Broncos must adopt in the away qualifying final clash with the Raiders on Sunday.
Former Broncos forward Ben Te'o is in charge of defence at the club and his methodology took time for Walters to embrace. Now he is a convert.
"He has changed up the way we wanted to defend this year in terms of what we call 'double defensive'," Walters told AAP.
"Ben has brought a different perspective which I probably didn't agree with at the start of pre-season. He just wanted me to back him and keep practising those reps and I feel like it has helped not only me but our whole team. We are defending better than previous years.
"It is a way of defending the Panthers have been adopting and the Bulldogs have tried to employ as well, and even the Warriors.
"It is about not taking yourself out when the opposition are doing block plays and being able to get both attackers. It is a tough thing to do and not everyone gets it right but the more reps we get in the better we will become."
Walters said the Broncos still had to back-up the Storm display and not revert to bad habits.
"It is something we have spoken about," he said
"We are very confident that we can score a lot of points against anyone but we can't be having games like when we beat the Cowboys 38-30 (in round 26).
"We can't leak 30 against Canberra. They are too good. We have had a big defensive mindset. The win over Melbourne was a confidence boost that we can do it. It's just about having the right attitude and desire to do it more than the opposition."
Walters has seen enough finals footy to know the best defensive team usually wins. Whether he plays hooker or No.6 he knows he has put the work in.
"I don't want to be a spot player," Walters said.
"I don't want teams to review games and say, 'we've got to get at Walters because he is a weak defender'. I keep that in mind and try to make my tackles so they don't come down my edge.
"It is a team effort. A lot of emphasis sometimes goes on the edges and people sometimes think they come up with the wrong plays but if you want to stop tries it is from everyone. If we can get that right across the whole park we will be pretty tough to beat."
