Brewers when behind in NLCS: .379/.514/.828 (1.341 OPS)
That's the best batting line in those situations in any best-of-7 series over the last 100 years (min. 25 PA trailing).
The Milwaukee Brewers are the first team in the history of American sports to get swept 0-4 in the postseason and then sweep that same opponent 4-0 the following year.
A “revenge sweep” has only happened 4x prior - never in consecutive 7-game series, and never in the MLB at all.
