Walsh played fullback in the 14-12 away win over Penrith on Thursday but right from the start of the match he went into a first receiver role and played as a virtual five-eighth.
It was a role Broncos legend Darren Lockyer often filled in his stellar career as a fullback before he transitioned to No.6 in 2004.
Walsh set up all three Brisbane tries against the Panthers and owned the attacking plays, despite the presence of starting halves Ezra Mam and Adam Reynolds. His left boot, like Lockyer, was also critical in putting the Panthers on the back foot.
The 24-year-old's influence can be gauged by the fact he made 61 passes and had 86 receipts in the match, almost as many as Mam and Reynolds combined, who had 69 and 96 respectively. Walsh also had 15 kicks for 495m compared to Reynolds (six and 188m) and Mam (three and 37m)
"Reece filled in as an extra half and I thought he was brilliant. Everyone is talking about it," Renouf told AAP.
"He does remind me of when Locky played at fullback. They both make it look like they have got all the time in the world and they are both precise with their passes."
The match winning pass by Walsh was a face ball thrown like a dart into winger Josiah Karapani's bread basket.
"The pass Reece threw to Karapani was a cracker. It is all about throwing it at the right time and getting it right when he does," Renouf said.
"Locky was exactly the same in that regard and the other similarity is the way they both move across the ground.
"When Locky played with me I remember watching him glide across the field and Reece is just like that. They can get into position in a small space to help make the pass count."
Renouf is sure that Walsh will one day play No.6 for Brisbane but for now his best spot is fullback.
"Reece can make the transition at some stage like Locky did but right now the more he has his hands on the ball the better we are," he said.
"With this dual role he is a virtual 'two for the price of one' and that is what Locky was as well. The way Reece was 'switch-in and switch-out' against Penrith worked so well"
The Broncos, now six points outside the top eight, must win their remaining seven matches to play finals but they will bridge that gap to just four points with a win over the eighth-placed North Queensland in Townsville on Saturday night.
"Everyone had them written off but of all the games they are going to play that one against Penrith was going to be the hardest," Renouf said.
"They can play finals. Why not? They just have to turn up like they did against Penrith week-to-week and hopefully no-one gets injured."
