From a Scottish perspective our tour was all about Japan next year, there are few opportunities between now and then to see who we've got behind the front rank players if they take a tumble before our first game of the tournament.
Scotland's front five in the Argentina game sort of resembles what we'd put out in a competition game, albeit only if WP Nel and the two Gray brothers aren't available. Playing our second choice hooker on the flank raised a few eyebrows, especially when we've got a genuine up and comer in Jamie Ritchie sitting on the pine, but that's Gregor Townsend for you. I guess he was looking at options within the limitations of the squad numbers allowed at the world cup.
We were also looking at where we sit regarding depth across the backline, and to be honest it doesn't look great. Young George Horne at scrum half looks good, though very inexperienced. Likewise Son-of-Gav at fly half looks promising but green. Who knows wrt to the centres? They struggled against the US and ran a really poor Argentinian defence ragged, Huw Jones and Alex Dunbar won't be losing sleep over anything other than their injuries.
Blair Kinghorn was a plus in the backline, he's gone from a callow Edinburgh fullback prone to the odd howler to a pretty useful attacking threat at this level, he turned 21 in January so there is still a lot more to come from him.
Overall, Canada and Argentina were woeful, and so were we against the USA, who were good for their win.
