Wales can give up ten points on the handicap against Scotland on Saturday evening.
Wales should give up ten points on the handicap to Scotland in the Saturday evening round two match. And it should be an entertaining encounter whether the Principality Stadium (rebranded Millennium Stadium) roof is closed (Scotland have suggested that they will agree in such conditions) or not, so back 45 or more points.
Wales have won the teams' last eight clashes and have been victorious in the last six Six Nations home meetings with four of these triumphs by a margin of 11 points or more and one by ten exactly. They are still the superior side and will be disappointed at only getting a draw in Dublin on Sunday after overturning a half-time deficit but delighted that an away point still gives them a start in their title challenge. The scoreboard totals for the last six Cardiff meetings are 54, 40, 55, 45, 46 and 43.
There will be no complacency in the Wales camp, with only a six-day turnaround, after they were bossed for long periods in last year's 26-23 success at Murrayfield and Scotland showed real promise in pushing Australia all the way for a World Cup semi-final spot. They know Greig Laidlaw's accurate kicking will punish repeated infringements in their own half.
Scotland were frustrated in their tryless 15-9 home defeat by England last Saturday but they still made several more gainline breaks than the visitors and were solid at the set-piece, which will not have been lost on Warren Gatland and his coaching cohorts.
Gatland's decision to pick the same side that started against Ireland shows that. It would have been easier to be cautious about the ankle sprain that forced first-choice fly-half Dan Biggar off at the Aviva and freshen up his pack.
What Gatland wants is more of the same stern defence that conceded only three tries at the World Cup against Australia, England, Fiji and South Africa and conceded only one in Dublin on Sunday for all Ireland's punishing first-half phase play through both pack and backs. And he also wants more patient build-up and heavyweight running from backrowers Justin Tipuric and Taulupe Faletau (scored Wales's try in Dublin) and centres Jamie Roberts and Jonathan Davies to create space and time for back three George North, Tom James and Liam Williams. Full-back Williams worried Ireland repeatedly with his jinky incursions into the line and deft grubba-kicks.
The dam is unlikely to burst like it did in two years ago's 51-3 hammering. Stuart Hogg was sent off after 22 minutes in Cardiff then and Scotland are a much more settled squad now with Kiwi coach Vern Cotter at the helm, quality southern hemisphere forward imports such as WP Nel and John Hardie bedded in and Glasgow and Edinburgh considered consistent threats at club level in the Pro12 if not yet in Europe. But Wales should still find a way to push clear. Gethin Jenkins, Ken Owens, Bradley Davies and Dan Lydiate offer proven forward power on the bench and young Exeter prop Tomas Francis showed up well at the World Cup and in Dublin when pressed into action. Backs replacements Lloyd Williams, Rhys Priestland and Gareth Anscombe are all adept at switching from structured tactics to expansive gameplans.
Scotland are becoming a serious threat but that potency currently seems to be coming at a cost. They conceded two tries to England last Saturday and were porous against Japan, South Africa, Samoa and Australia at the World Cup.
