Leicester – depleted by eight World Cup call-ups from their forwards – also fell to the Sale Sharks a week earlier but Richard's remains upbeat about the trip to Leeds.
"We're still quite buoyant," the coach told the Tigers' official website. "But we're playing an inexperienced side, and while that sometimes works, occasionally it doesn't.
"Inexperience is one thing, but we've also lacked nous at times, having an appreciation of what to do in a game, going through with drills.
"We're a bit guilty of not actually making the right decisions or not trying to go through with things, but we're not finger-pointing – the players are their own worst critics."
Despite last weeks heavy loss, Richards makes one change only, with Brett Deacon returning in the back row at the expense of Adam Balding.
Tigers face a Leeds team placed just one spot below them at ninth in the Zurich Premiership and both are tied on 10 points.
"I'm still of the opinion that we have nothing to lose," said the coach.
"When sides play against Leicester there seems to be more intensity from them than when they come up against others.
"People aren't expecting anything from us because with the World Cup and injuries we have about 13 or 14 people away. We just have to play rugby."
Of a Leeds side, who ran in six tries during their last match – a 41-31 home win over Saracens – Richards said: "They've been a bit up and down, but they were good in their last game. They've always scored tries and been a difficult side."
The Tykes will welcome back veteran Mike Shelley for the match after injury, and the England 'A' prop is a man for whom Richards has the utmost respect.
"He's a key player for them – an inspirational leader," he said. "They stayed up last season when a lot of people thought they might not, and he was instrumental in that. He's a nice guy and he leads from the front.
"But Leeds are a good side generally anyway. They're very abrasive and have a good line-out. They could cause problems, and in Dan Scarborough at wing or fullback they have one of the best finishers in the game."
