You're really just guessing about "could very well disrupt the progress." I think you're looking for a negative angle -- with no evidence that a negative angle is applicable.
But at least you do have a built-in excuse if we do struggle early in the season. You can now blame it on playing across the pond. I'll instead suggest it's because Frost isn't a good coach. Of course, winning will put all of that to rest.
Anyhow, it's really not worthy of our debate. The game is on the schedule to be played in Dublin.
I don't even think it needs to get to that part of the argument about Frost, etc. It's a great opportunity for these players to experience something most will never get a chance to ever again. They do DESERVE it because they've put in a ton of hard work. Win/loss record is irrelevant to that part of the discussion involving the players.
You and I (and probably most here) are happy they get that opportunity.
