Toughest debate about Ireland team to play Scotland involves Jordan Larmour
Ireland may opt for a more dynamic, unpredictable presence for the Scotland game.
On Monday morning, Fergus McFadden was back on the training pitch for Leinster.
Leinster are away to Scarlets this weekend [weather allowing] and McFadden is in need of a decent run out. He has done well for Leinster this season but even if he does register a decent performance in Wales, his position in Ireland's matchday squad for round four of the 2018 Six Nations must be in doubt.
McFadden is often seen as a safe pair of hands and he is someone whom Joe Schmidt places a lot of faith in.
That is merited, on past outings, but his last two sub appearances for Ireland have not inspired confidence. Against the French, in Paris, McFadden and Rob Kearney were the least involved in that 41-phase drive to set up Johnny Sexton's drop goal.
Whereas Keith Earls threw himself into rucks and backed himself to make a big play [the crossfield kick], McFadden only had one carry and a couple of ruck involvements. In fairness to him, he stayed out wide to stretch the French defence.
McFadden got a longer run of it against Wales - 18 minutes - but he struggled to make a positive impact on the game. McFadden is registered as having only one carry, for a metre gain, and missed his only one-on-one tackle.
On 70 minutes, after a decent Kearney counter, he took contrived to knock-on a pass popped back to him when he was under minimal pressure. It gave the Welsh a scrum in a dangerous position but Ireland weathered the storm.
Then, less than a minute after Conor Murray's penalty made it 30-20, McFadden was guilty of biting in on the charging Scott Williams and leaving Ireland vulnerable out wide.
As we can see below, McFadden was drawn in on Williams  but he should have left him to Bundee Aki. As it transpired, Williams was able to get the offload away to Josh Navidi, who then drew in Kearney and slipped in Steff Evans for an easy score.
Ireland defence coach Andy Farrell said, in the lead-up to the Wales game, that average was not acceptable. McFadden would have put his hand up after those two unfortunate slip-ups but that may not be enough.
McFadden is a goal-kicking option but, when Sexton was not used, it was Murray that took that 74th minute penalty.
The No.23 position looks, once again, to be tricky for Ireland.
Andrew Conway's knee injury is taking longer than expected to get right so he is unlikely to feature, while Leinster's Adam Byrne is also out injured. Schmidt has had 20-year-old Leinster star Jordan Larmour back in for training with the senior squad so he would appear to be McFadden's biggest threat. Rory Scannell could also feature.
The other options are men who have been there and who have done it for Ireland before - Tommy Bowe, who can also cover centre, and a talented Cork lad who is off to France this summer, Simon Zebo.
Zebo would be the best bet, in our opinion, but Schmidt appears to have bolted that gate and reversed a truck up against it.
