Because over however many years, especially against Ireland, that has been their Achilles heel.

Now, you touched on it earlier, Joe.

They're missing both of their first-choice locks.

Now, I think that is...

That's massive for them because Max Williamson and Grant Gilchrist are going to come in to replace Gregor Brown and Scott Cummings.

But that also has a knock-on effect for their bench and what they're able to bring on in the second half.

Now, you could say that that's slightly offset by James Ryan's loss.

And again, I agree with Ian.

I think he is a massive loss because I think all things being equal, I think James Ryan would have started the game this weekend and you would have seen Tygburn at number six.

So Ireland were planning, as far as I'm aware, to pick three locks to target Scotland's line-out.

Ireland have the joint best line-out in the Six Nations League

this year, which is kind of gone unnoticed.

Paul O'Connell was under pressure last year, but it's kind of gone unnoticed how much improvements have been made there.

And conversely, Scotland have the worst line-out record in the Six Nations.

Now, I don't think Jack Conan weakens the line-out by any means whatsoever.

I think he's an excellent line-out forward, and if anything, he deserves to keep his place in the team last week.

But I would still have question marks

over Scotland's ability to live with the Ireland pack, particularly without their first-choice locks.

You look at how well Jack Dempsey played last weekend.

Can he go again this weekend?
