Wallace couldn't hide his disappointment at the attendance figure of 21,301, and can't fathom why there wasn’t a bigger turnout.
"I was really disappointed with the crowd. I wasn’t disappointed with those who were there, I think they made a heck of a lot of noise for Richo's 200th game, I thought they were fantastic," he said.
"But I would have expected more than (21,301) at the venue for Richo's big day, so we were probably disappointed from that aspect and so it wasn't as big a build up.
"For some reason, people didn’t come and didn’t front up to the match, maybe that was the manner in which we played the week before, I don’t know."
Wallace sees as disappointing is the fickleness shown by the supporters - but he does realise, with the club's 2004 performance, that their apprehension is justified.
"I think at the moment, because where we have been as a club, we're inclined to get a few fair-weathers at the moment, who will jump on if its going alright, and jump off if its not going so well," he said.
"I think we need the support and the rest will come along, but unfortunately people will make the decisions by walking though the turnstiles or not."
Wallace said he expected the Tiger Army to be out in force for Saturday's clash against Carlton at the MCG.
Meanwhile, Wallace has played down the notion of a premiership hangover, suggesting that Port Adelaide's poor run has more to do with a shortage of quality players.
"Just that they haven't got the same personnel on the park, that's the main thing," Wallace simplified.
"You lose a player the quality of Nick Stevens 18 months ago, you multiply that and lose Josh Carr, take Roger James out of your line up, and you play two midfielders who have missed 18 months of football.
"That just changes the whole of the side, and I think most of us sort of say it is midfield dominance that sets up games."
Wallace acknowledged that in facing a vulnerable Port side last Sunday, Richmond had been granted a rare opportunity, and he was pleased his players were able to take it.
"We were very happy to be getting them at the time we got them, we were aware there were opportunities there, and we hadn't beaten them for seven years," he said.
"There was an opportunity, and it was just whether we could take up that opportunity. The way we went about in the first quarter, I didn’t think we were going to be taking up any opportunity at all."
