Unless you think they are just deciding to swing at everything and their strike recognition ability isn't the real reason and isn't impacted by the size of the zone and borders. This isn't complicated...a smaller strike zone will lead to more walks across the board, and a bigger one would lead to more strikeouts across the board. But that's not what you were saying a minute ago. You were saying it would somehow negate a Cubs advantage, or that somehow it would help others more than us. But if walks increase across the board...for teams that aren't all that patient AND for ones like the Cubs that are, there's no real loss...and if anything, there's a gain from the Cubs being able to now hit more balls in the zone. Read the edit. And I acknowledged that the change MIGHT (we have no real way of knowing this) be offset by better utilizing our power. But it could very easily result in a less drastic advantage in terms of walk rate and OBP.
