I think we all take your point and agree to some extent but the reality is this tour is only costing us Baloucoune out of the starting XV and two probable subs. Yes it weakens us but wing is a position of relative SID for us so we have decent options to cover BB. At 9, yes Doak would have benched ahead of Shanners but lets not pretend Doak is the finished article - he isn't going to win us a game that we weren't going to win with Shanahan. Likewise, we have cover at Centre/Utility Back so not having Moore on the bench isn't the end of the world.
To put it another way, if we lose, we will struggle to blame emerging Ireland. We are more likely to feel the loss of Hendy, DV, and Hume (nothing to do with Emerging Ireland) than Baloucoune and Doak.
This will be the closest to a full strength contest we have seen in years and I am hugely looking forward to it. My prediction is we will make a real game of it. I don't think Leinster will be travelling with undue optimism, they will be expecting a tight game that could go either way, which is saying a lot considering they will be bringing much of the Ireland team who just beat the ABs in a test series.
