I agreed with most of what you wrote, but in regards specifically to the statement quoted above…I prefer an effective team over a so-called “balanced” team. I want a team that can adjust to what the other team is doing. and etc.
I really don’t see the alleged “balance” of a 222 team as being an advantage, I see those restrictions as a disadvantage, albeit I’ll of course concede that in 222 both teams are weighed down by that same disadvantage
