First comment on the squad.
I know we(Wales) have a rather large contingent, but they're mostly multiple copies of the same position. Ok, Scotland somehow beat us, but of the Welsh players going, there's maybe 1 or 2 that Scotland could say 'our guy is as good'. The bulk of the positions are covered by England (which is pretty spot on), but there is then quite a nice bit of depth taking from the other nations.
Launchbury not going is probably a bigger shock than any Scot not going, and that's because there is an absolutely ridiculous number of top quality 2nd rows at the moment.
If Hogg wasn't picked, then I'd understand completely, but I can't see a single stand out player that isn't in that squad (apart from the aforementioned, and even then I can see why).
Personally going to try my hardest to take my Welsh hat off for the next few months (and urge others to also hope for a very small meteor landing on Premier Rugby HQ, who may be the biggest threat to the Lions there has ever been).
