I don't know whether Italy on Saturday is Wales' biggest game in 20 years. There have been World Cup semi-finals and Grand Slam deciders.
But this is big for a different reason. It's big because of where Wales are. They've lost 13 on the bounce and, even this early in the tournament, this is the wooden spoon decider.
You're looking at this game and thinking it's hard to get your head around where Wales are and where they've fallen from.

Even if it isn't Wales' biggest game for two decades, it's certainly a huge selection for Warren Gatland. Gatland has usually got his selection right, but this is a big test of his decision-making after Friday night.
With Owen Watkin out injured, there'll be changes to the backline anyway, but I think he'll have to sacrifice a big centre and go for two kickers. That is where Wales were lacking on Friday night in Paris.
Looing at the French defeat, the first thing is I don't think the boys can give any more. That wasn't far off our best team. There's no one really captured by the 25-cap rule, other than Joe Hawkins - who isn't really playing for Exeter.
So this is what we've got and where we're at. We created a couple of chances early on, but unfortunately we didn't execute them because we didn't square up the shoulders and commit defenders. We were far too deep and far too lateral.
Shaun Edwards played it right on Friday. France came up as a unit and just absorbed the Welsh attack. They didn't overcommit, but they just let Wales play behind the gainline and stopped them.
Put simply, we overplayed. We were chipping over the top in our own half and doing little things like that. Sometimes, you've got to play the percentages and kick to the corner to turn teams.
The problem we have is we don't have many kicking options in this team. Beyond Ben Thomas, we haven't really got anyone in that backline. Liam Williams doesn't kick all that much as a full-back, while there's no real kicking option in midfield.
It's hard to have a good kicking game if you haven't got those options. There's also not much deception in what Wales are trying to do. We can't outmuscle sides, so we need that. You need forwards who can tip-on passes and make right decisions.
Look at Dan Sheehan for Ireland on the weekend. He's making decisions. You can't just take it up and get smashed back. The forwards are taking the ball behind the gainline, losing collisions and making life harder for themselves.
They've got to play flatter and play on the gainline. Otherwise, it's just playing rugby on a treadmill, where you do a lot of running and go nowhere.
On Friday, Wales at times kicked for the sake of kicking, without any connection. It's the choices they're making with the kickers they've got. Wales didn't put pressure on because of it. It'll be interesting to see what they do with their centres now.
Do you go with two big carriers? Or do you put Ben Thomas in there, so you've got another kicker in Dan Edwards in the backline? It's perhaps where Wales have made a mistake not selecting Gareth Anscombe and Max Llewellyn, because at least they've played with Tomos Williams at Gloucester.
If he puts the two Scarlets centres, Eddie James and Joe Roberts, in there, you probably still need another kicking option in the backline, although Roberts has a decent left-foot. But look at Ireland, who have James Lowe offering that from the wing. Scotland have Blair Kinghorn kicking from full-back.
They have options. We don't have that. But Wales can't overplay. They need to frustrate Italy. The pressure is on them. They're favourites and the fans will expect them to win. It's a different position for them. So you have to create that pressure on them.
Wales have to do the basics well. Defend well, kick well and be solid at the set-piece. That'll put pressure on Italy. Otherwise, if they do what they do on Friday, they'll just make a rod for their own back.
Italy go in as favourites on Saturday. They played well against Scotland, although Finn Russell was loose. He said as much afterwards. Wales can't be that loose. They need to play in the right areas and not give any leg-ups to the Italians.
They won't outmuscle Italy, so they need to outthink them.
But I really worry about the game management. International rugby is all about managing the match, making the right decisions at the right time and not putting yourself under pressure. If things don't work out, you have to have patience and shift the pressure onto the other team by being smart. Right now, Wales are just not doing that. To manage the game, you need kicking options, centre partnerships, deception to dictate tackles when you haven't got brute force. Wales don't have that right now. They need to find a way to do it. It's a coaching problem, ultimately.
They got caught on their own line from a simple exit strategy in Paris. That should be easy to execute, but Wales don't have the options and France were able to read it and disrupt. I just don't understand what they're trying to do.
Ahead of the trip to Rome, they need to come with a real good gameplan. Sam Warburton spoke about easy fixes for this Wales team and he's right that there are some.
However, you can have all the easy fixes you want, but they don't come off without game management and execution. That's what Wales need to get right this weekend.
It is undoubtedly difficult times right now but it goes without saying everyone will be behind the boys in Rome and hoping for a much-need confidence-boosting win. Good luck to them.
