Former England player Duncan Bell would not have fancied coming up against Jamie Roberts:
74,000 or so Wales fans are singing hymns and arias, serenading their team in these final 12 minutes. Goosebumps.
Wales mess up their own line-out, but WP Nel fumbles, which gives the hosts put-in at the scrum. Oh, and what's this? A penalty to Wales. Stuart McInally the offender and Biggar will have the opportunity to kick his team into the opposition 22. Silly.

"Pressure, pressure, pressure. Great running on to the ball from Jamie Roberts. He runs on the blind-side shoulder of Nel to score."
Wales 20-16 Scotland
Wales delay a tad too long, Scotland surge forward, but the hosts come away with the ball... it's a little messy but the 17-stone Jamie Roberts brilliantly times his run, bursting forward, crashing through two defenders and diving over for his 10th Test try. An easy-peasy conversion for Biggar.
Well-matched? You could say that...
Waves of red crashing into Scottish bodies. The charging Jamie Roberts is released by Gareth Davies, but the centre is brought down 3m short... Jonathan Davies is stopped... Justin Tipuric stopped... brilliant tackling from the visitors... no way through...
Scotland concede a penalty - but Wales turn their nose up at three points and opt for the scrum in front of the posts.

Andrew Priestley: Incredible tackle from Duncan Taylor. World-class.
Miss Moz: What a tackle from Taylor!!!
Decibels rise inside the Principality Stadium as Gareth Davies prepares to feed into the scrum with his forwards 5m from the Scottish line. Could be the crucial moment of the match?
"Wales! Wales!" cry the crowd...

"The Scotland bench is not as strong as Wales'. When Scotland's replacements came on last weekend they came off second best. These guys are professionals - why would you substitute your best players after 65 mins?"
Loose ball! Tom James sneaks down the blindside... the Cardiff Blues man like a greyhound down the left wing, gaining acres for his team - but with the tryline looming he's stopped by a try-saving tackle from Duncan Taylor.... A crossfield kick, George North fails to collect, the supporting Liam Williams kicks into touch and a fabulous chance dies a death.
Wales 13-16 Scotland
Jonny Gray with a fabulous tackle on Liam Williams as the full-back, having gathered the high ball, threatened to break loose. Scotland earn turnover ball, but opt to kick... Jonathan Davies gathers, but opts to kick... Wales lacking adventure.

"There’s a lot of aimless kicking going on. Someone needs to take this game by the scruff of the neck."
Wales 13-16 Scotland
"You're both down too early," says George Clancy to the front-rowers. Eventually Greig Laidlaw gets the ball in, Scotland immovable, and Wales are penalised for not binding.
Greig Laidlaw, in front of the posts, 23m out, could kick this one in his slippers. He decides to do so in his boots, and puts Scotland in front.
Oh Liam Williams. The Scarlets full-back fumbles the bouncing ball. He shrugs his shoulders as if he's unaccustomed to knocking the ball on.
Scotland with a scrum within touching distance of the Wales 22... they earn a free-kick and decide to pack down once again.
There's no structure, it's helter-skelter.
Liam Williams' kick is charged down... Welsh hearts beating faster... but the men in red scramble in defence, boot the ball away and Ruaridh Jackson lets the opposition off the hook, stepping into touch to gift the hosts a line-out near the halfway line.
There's a man in the crowd dressed as a dragon. He doesn't seem embarrassed, content to wave the national flag to the nation.
A triple substitution for Wales, Bradley Davies, Ken Owens and Gethin Jenkins coming on to add experience and bulk to the pack.
Wales 13-13 Scotland
Gareth Davies collects the bouncing ball... turning defence into attack, feeding George North who weaves into Scotland's half, zig-zagging away from Scotland defenders before he's eventually stopped by the brave Alasdair Dickinson. North in full flow, a beautiful sight.
A penalty to Wales it is, though. Dan Biggar in front of the posts. The Ospreys' man doesn't miss from there.

"If the Welsh forwards front up - if they can get the likes of Taulupe Faletau running forwards - they will win it, but at the moment they're not in it."
John Hardie runs into the road block that is Jamie Roberts and is pushed back, but the Scotland flanker holds tight to the ball, allowing his side to recycle possession, chipping into touch.
Wales with a line-out inside their own 22. Pressure. But the Scots disrupt it illegally, closing the gap, and Wales have a free-kick.
