Well, you present this as if squads weren't part of a team, which they are. And they are not playing for the sake of entertainment, they are playing to win.
My take: when you face someone who goes for a high-risk-high-reward strat, you dont beat them by *****ing about it pre-game. You beat them by exploiting that high risk to your advantage and hitting them where they are exposed. The problem here is i am not sure many can actually exploit that against them. If that is the case (big if, I concede) then it is no longer a high-risk strat anymore. It is just a good bloody strat. I believe, to some degree, they are testing that out. They have a plan, they believe they have the players to pull it off, they are playing against someone who on paper could make them pay for it and, worst case scenario, they are still in 1/4 finals. I might not like it, but i do see quite a lot of sense behind their decisions.
And again, and i cant stress enough how relevant this is: they have no surprise factor to play around with.
