Gordon was part of the side beaten 23-9 at The Millennium Stadium last weekend and is aiming to make amends against the Irish in his first game in charge.
"If you don't win games, you don't gain confidence - that's a fact in any sport," declared Gordon, who will take over from Scott Murray after the lock suffered a knee injury in Cardiff.
"The game against Wales was a set back, but we have talked about it. We have watched the video and we have cleared our minds and we know what has to be rectified. We have a good group of guys and we have to believe in ourselves and have a go at them.''
Meanwhile, Gordon also claimed that the sacking by Borders of Richard Metcalfe showed why the nation's professional rugby players should form a union as every other major rugby nation has.
"Richard has been released after suffering a horrible injury and it is always at the back of your mind that these kind of injuries can happen to you and maybe threaten your career.
"We wish him well. I still think he's got a chance to play again, but it's going to be a long hard road for him.
"We've been talking about the need for a players' association up here for a while," he observed. "It's been very successful in England where they can fight the cases of guys who feel they've been harshly done by. We now have to look into it through people like Andy Nicol who have just retired, know the players well and can deal with their welfare."
Metcalfe voiced his disappointment at having his contract terminated but said he wanted to offer no further comment before consulting his lawyers. However, Bulloch feels it only underlines why Scottish players need the kind of separate representation available to those in every other major rugby nation.
"You are talking about a business deal now," Bulloch noted. "I'm afraid we are commodities and if we can't go on to the pitch at the weekend we are not a useful commodity. That is why an association is definitely needed. You just have to look at the English Premiership where players pay a certain amount into a fund to have legal support and advice available."
