Ireland U20s: Redemption can be found
Ireland coach Nigel Carolan will stress the importance of not fading out of the Six Nations with a third successive loss.
The changing of both locks against Wales backfired badly, thus the return of David O'Connor and Alex Thompson and the return of Josh Murphy to the back row with Nick Timoney at openside.
There is also a start for Conan O'Donnell at tight-head as Ireland bid to repair the heavy damage done by Wales at the set-piece.
The inability of Ireland to establish any firm foothold meant the backline was unable to breakout of Wales strait-jacket defence.
Half backs Nick McCarthy and Ross Byrne can work the oracle if they are given a break-even return up front.
The Scots have set a target of winning their three home matches. Wales and Italy have already felt their force.
