Saying Look Inside should lose to 2-3 zone if both teams were the same is incorrect.
First, the team playing LI also plays defense, and the team playing 2-3 zone has to play offense, too.
So LI/3-2 against RNG/2-3: Both teams should win?
Second, it's not enough to say both teams are the same. The players' actual skills matter.
And lastly, there is the transition game. You can't say for example, my RNG beats your M2M 8 to 5 but your Motion beats my 2-3 zone 6 to 2 so you add it up and it give you 8+2 - (5+6) = -1 so I lose. If only it was that simple, but defense is offense and offense is defense, and until we have sliders for how much we want to crash the boards or how much we want to get back in transition or leak out on the break, we have to do with what we have and figure out why things are the way they are.
