The 6ft 7in former international lock is a team man and, as the lone member of the senior backroom team that took Warriors to the RaboDirect PRO12 play-offs twice in three years to avoid last season's cull of professional coaches, he was never going to shirk his responsibility.
"This time last year it was exactly the same," said the forwards coach of the way the team's malfunctioning lineout had contributed to an opening-day defeat in the league. "Partly it is to do with thinking we've cracked it in that department when we haven't, partly it is to do with it being the first game back for some players who have not been available for the pre-season friendlies and partly it's my fault, which is probably the biggest factor. The execution of the calling, the throwing and the jumping were all poor.
"We're not known as a team that has a problem with the lineout and no matter what we plan to do from the lineout it's my job to make sure we get good possession from there. We just weren't good enough.
"There have been a few honest words said to one another and we're under pressure a bit this week and we have to get it right."
That, of course, applies across the board if the winning environment generated under Sean Lineen last season is not to evaporate as they make their first appearance at Scotstoun Stadium.
Lineen's Warriors suffered only four more defeats after their opening-day failure to register a bonus point at Ulster last season which is consequently the minimum benchmark, along with a second-place Heineken Cup pool finish, for the side under the new head coach Gregor Townsend and Matt Taylor, the defence coach.
However, Munro believes little has changed in terms of expectations.
"You are always under pressure in the Pro12 and that would have been particularly the case in the first home game anyway," he said. "Now we've doubled season tickets and everyone is excited about the move to Scotstoun it has to be positive and it has to be a win. When you're in this environment with your coaching team and your squad we're all pulling in the same direction knowing we've got to perform.
"You get new ideas. With Matt coming in there's a different way of approaching the defence and the attack will change a bit under Gregor but they've got to be provided with decent ball to attack with."
In spite of the early-season defeats, the mood remains vibrant, according to Munro.
"The guys are very much looking forward to playing here," he said. "There may be a few teething problems but they are mad keen about the venue and, speaking to friends in Glasgow over the summer, I think everyone's very excited about coming to see it.
"It is a very different venue from the one where we played a few games in the early days of professional rugby. The training pitch is outstanding, we've got the 3G [artificial] pitch here and it's the first time we've had everything together after all the years of training and playing at different venues around the city.
"The whole thing is about trying to create a club atmosphere and there will be a clubhouse for supporters to have a beer in as well. I think it is fair to say the West End lot were never that keen on Firhill so this move is to a more rugby specific environment. It may be an athletics venue, too, but we are the main tenants and this is going to be the base of the Glasgow Warriors so there is a real buzz around the city's rugby community."
In regards to that, he seems to want to tap into the most visceral elements in comparing this week's match against a Llanelli Scarlets side that put European champions Leinster to the sword last week, with a derby rivalry. "The Scarlets are a lot like Edinburgh. If you let them do it then they can play the game outstandingly well, Leinster were not at full strength but they weren't 40 points bad. They stood off them a bit and really paid the price by letting the Scarlets show the way they can play.
" 'Get intae them' is a good way of putting it. I'll be passing that on to the players."
