Wales interim head coach Rob Howley: "There were too many unforced errors in our game [v Scotland] from 40 to 55 minutes, after a really dominant first half on the back of one of the best games in the Six Nations against England".
With the knowledge that defeat could put them at risk of dropping out of the world's top eight ahead of May's Rugby World Cup draw, Wales started the game at break-neck speed.
"Friday is an opportunity for us".
Wales suffered against Scotland openside Hamish Watson in Edinburgh and are wary of a varied approach from tonight's guests.
Backs: Leigh Halfpenny; George North; Jonathan Davies; Scott Williams; Liam Williams; Dan Biggar; Rhys Webb.
Wales secured the win with a try through replacement Jamie Roberts, converted by Halfpenny. As I've said in previous blogs Wales have some unsafe players in their backline, as well as strong and creative ball carriers in their pack.
Ireland has won four of its last six matches in Cardiff, but its Grand Slam hopes foundered in a loss in the Welsh capital two years ago.
"For myself, personally, there is still a level of hurt there from the Scottish defeat, and I am sure the players are feeling that as well, so we need to react in a positive manner against what will be a very confident Ireland team". Perhaps this is a new experience for this squad of players, but they have got to come through it.
Vince Young did not receive signing bonus from the Saskatchewan Roughriders
Young was so enthusiastic about his comeback that he actually filed for a trademark on the phrase, "Make Vince Great Again". In 2007, Kerry Joseph won the CFL's Most Outstanding Player award and led the Roughriders to the Grey Cup title.
Since then Ireland have lost nine of the 13 games Barnes has officiated and left many Irish fans scratching their heads over any number of contentious decisions.
Barnes didn't have one of his best games in 2015 but neither did Ireland.
He made two linebreaks with his 14 carries against Scotland, one of them involving a powerful fend after a clever dummy pass to Paddy Jackson as the out-half ran a loop play.
It will be interesting to see if they opt for more of the same if awarded a penalty inside Johnny Sexton's range during the opening stages in Cardiff.
New Zealander Schmidt announced his side on Wednesday with the only change on the bench as Ulster wing Andrew Trimble was ruled out of the remainder of the tournament with a hand injury and is replaced by club mate Tommy Bowe. Countless times they turned down kicked at goal to go for the corner. Smart play from Scott Williams and Rhys Webb, with a attractive wide pass to Leigh Halfpenny, meant that the Irish defensive line was back-peddling by the time North got his hands on the ball.
Replacements: 16 Scott Baldwin, 17 Nicky Smith, 18 Samson Lee, 19 Luke Charteris, 20 Taulupe Faletau, 21 Gareth Davies, 22 Sam Davies, 23 Jamie Roberts.
Ireland: R Kearney (Leinster); K Earls (Munster), G Ringrose, R Henshaw (both Leinster), S Zebo (Munster); J Sexton (Leinster), C Murray (Munster); J McGrath (Leinster), R Best (Ulster, capt), T Furlong (Leinster), D Ryan (Munster), D Toner (Leinster), CJ Stander (Munster), S O'Brien, J Heaslip (both Leinster).
