If Ulster lost against Connacht when sat on the sofa, then there must have been times against Leinster on Saturday night that they wished they'd gone back and looked under the cushions for whatever it was they left behind.
This is a better than decent rugby team - their body of work over the past two years, if not the past two weeks, confirms the fact - yet just one week out from the PRO14 semi-finals and the most important game of their season, they have all of a sudden developed a propensity for the most basic of errors.
Or at least, as sudden as a six-month lay-off allows. After such a lengthy break, a degree of rust was to be expected, hardly helped by missing training this week thanks to the outbreak of Covid-19 in their Academy, yet there will still be a concern at how they have been afflicted so much more severely than their Irish rivals.
In the first-half, they were held without a point. Again, for every promising strike play there was a fumble or mental mistake that abruptly switched the foot from accelerator to break, all the while proving the old adage that errors are contagious.
How else do you explain sights like John Cooney box-kicking out on the full, Marcell Coetzee passing to nobody in particular and Stuart McCloskey losing the ball in contact? Those three haven't just been Ulster's best players this season, they've been among the best performers in the entire league.
This was not the write-off of the week before thanks to a much more spirited display in the second-half, one that had them in position for an unlikely comeback until George Clancy controversially called back Cooney's try for offside when the conversion would have made it a one score game - a decision that bemused Ulster's head coach Dan McFarland.
But nor was it of a standard to beat Edinburgh in Murrayfield this weekend when the stakes are raised to do-or-die.
"I don't have an answer for why we made that many errors in the first-half," said McFarland after what was his 50th game in charge of the northern province.
"I'm watching the guys in training and we're playing at an intensity level and a speed that would be faster than anything we play in (a game) without making those errors.
"One of the things is ball security, we're losing the ball in contact which is not something you see in training.
"Perhaps that's something I've been remiss about, not emphasising that we need to be better at not having it stripped or losing it in the tackle.
"It's things the players are capable of doing. If you're losing the ball in contact at this level, it's not because you don't have the skill, but it might be the nature of the emphasis in training means that I haven't put enough importance on it.
"Maybe we haven't created the scenarios in training that put them under that pressure so that when a team really stresses it, it becomes an issue.
"It's not something that takes six months to solve. Lets hope it only takes two training sessions."
With Jacob Stockdale and Jordi Murphy limping off for a side who are already without Iain Henderson, Robert Baloucoune, Luke Marshall, Will Addison and Sean Reidy for the trip to Scotland, it's hard to imagine just how bleak their prospects may have seemed if not for the marked improvement in intensity after the turn.
"There's an encouraging sign in that there was a buzz and a zip in that period and even before when we did string it together.
"We looked much more like the team that got in this position.
"We were moving the ball, running hard, finding the edges, we looked like that team again against what we know is a really good defensive outfit. But we have to knuckle down and be aware that simple errors kill your ability to maintain pressure on an opposition."
While they don't have the depth to beat you with a second string as Leinster did here, Edinburgh are a resolute outfit defensively themselves with the likes of Blair Kinghorn and Duhan van der Merwe plenty capable of asking questions in attack.
One thing Ulster will hope they don't have to deal with this week at least is the uncertainty that those eight positive Covid-19 tests among the Academy crop brought upon their set-up.
Having been off on Monday, the players were sent home on Tuesday and could not return to training until Thursday when they were granted the all-clear.
With players from the underage set-up training and traveling with the senior squad, it is no exaggeration to say that their entire season, given their place in the knock-outs of two different competitions, hinged upon the negative tests that were returned to the panel only two days before taking the field at the weekend.
"It doesn't make it any easier but these things might happen, we're all aware of that," said McFarland.
"We'd rather it didn't but you have to get on with it. It's not a factor (in the loss). We trained once during the week but we weren't really intending to train more than once anyway. We were going to have a bit of a session on Tuesday when we had to go home.
"The biggest thing is waiting for the results.
"It played on my mind, I'm not sure about the others, but it certainly played on my mind and the mind of the docs.
"But it's been on my mind every week since we've been back, every time we've had testing. It's difficult times but we're getting used to it."
No excuses from the head coach it seems, likely understanding they'd count for little come this weekend anyway.
His side are much better than they've offered the past two weeks. The problem in this most unusual of seasons is that they're fast running out of time to show it.
