Canada shouldn’t have been doing this. But on the flip side, is there a sport where you glean less from this type of activity than soccer? Maybe you get an idea of the setup but how many times do teams spring something totally different in a key spot? Ok, there’s been Pep and City but that often led to a poor result and that’s not the international game where managers are much more risk averse.
Maybe you can pick up if a player is struggling in practice or a training ground free kick play. But, soccer, to me, is the ultimate players sport. Players are given guardrails but with the free flowing nature of the game and limited subs, it’s up to the players.
