Of the many things we've learned in Ireland's first two Guinness Six Nations games, it's that the depth at tighthead is better than we'd given it credit for.
With Tadhg Furlong missing the opening games of the championship due to a calf injury, Ireland still haven't missed a beat.
Finlay Bealham has stepped into the starting 3 jersey and played like he's owned it for years, doing the nuts and bolts front row work, and combining it with a ferocious appetite in defence.
The Connacht prop emptied himself in his 60-minute shift against France yesterday, but crucially there was no drop-off after that.
The 32-19 win against France said a lot about the depth in the Irish squad, with pretty much all eight replacements making significant contributions. Tom O'Toole - who replaced Bealham just after the hour mark - may well have caught the eye more than any of them.
The Ulster prop has had to be patient for his chances in an Irish shirt. He's been a consistent presence in Irish squad since the 2021 Six Nations, but yesterday's win against France was just his sixth senior cap.
And after producing his best Irish performance in his first home Six Nations game, he says there's no doubt it's the highpoint of his Test career.
"I'd have to say so, it definitely was [the high point]. In terms of Six Nations, playing for Ireland it doesn't get better than that, does it?," he said.
The Drogheda native, who grew up in Australia before returning to Ireland as a teenager, showed just how dynamic he is on the ball with an eye-catching eight carries for more than 50 metres in just under 20 minutes.
And having broken a tackle with his first touch of the ball, he says it gave him confidence to keep looking for it.
"Absolutely, it was one of the days where the ball comes your direction, and you just have to take it. I was excited on the bench, excited on the occasion, and coming on at 60 minutes you have 20 minutes to play in a tight game.
"We kept talking on the bench, saying we need a bit of spark and energy, fortunately I got myself in the right positions and the ball was coming my way. I had to step up for the team and just carry as hard as I could.
"When you get in, and get on early, you just want to get involved. As a bench player you're watching the game, trying to pick out areas in which we could attack.
"Fortunately I got it a few more times, I was just excited getting the ball and carrying as hard as I could."
Prior to last week's game against Wales, O'Toole was namechecked by Farrell as a player he wanted to see make an impact in this championship, with the 24-year-old given his Six Nations debut in Cardiff last week.
"He's been a project for a while and you get to that stage where you can't keep chasing potential," Farrell said at the time.
And it's clear that feedback has been given to O'Toole, who says he was determined to make his chance count.
"I think for me, I've been in and around the squad for the last few years, and it's time to step up, and time to show that I'm capable at this level.
"Tadhg [Furlong] is world class and a great leader for the team, and Finlay has done exceptionally well coming into that role, so it was time for me to step up and add to the team, that's all I wanted to do. It's a great opportunity, but I needed to come on and have an impact, and add bits and pieces for the team.
"It's been a great opportunity for me at this level, and at the stage I'm at in my career now, it's definitely time to step up. I was excited to get the opportunity today and fortunately it went well.
"I think with Andy and the rest of the coaches, we knew what we were working on. Behind Finlay [Bealham], and behind Tadhg in the last couple of years I learned a lot from those guys. It was just being patient.
"Definitely coming in I was a bit more ready than I had previously been. I definitely know the environment and I knew what Andy wants from me. That's all I really wanted to do, get an opportunity to show that I've been wanting to learn, eager to learn. Hopefully I showed that today, but it's just the start. There's plenty more work to do."
While Furlong hasn't featured due to a calf injury, the tighthead has been training regularly with the squad, as he works his way back to fitness, rather than rehabbing the injury out of camp.
And O'Toole says it's been invaluable having the British and Irish Lion by his side, helping prepare the team.
"Being behind Tadhg has been class, he's the best tighthead in the world, and his leadership within the team, he has a massive, massive role.
"For me to learn off him, and as soon as he realised he wasn't fit to play, he just switched completely and wanted to help out in any way he could, made sure I was ready across my detail, that he'd go through stuff with me, he's been absolutely exceptional.
"That's the type of character he is. Once he's back fit, he'll fit back into the team and will do what he does best, but he's been really, really helpful, making sure we're ready, a team-first attitude and mentality."
