Should the Cubs manage to win perhaps, playing the Brewers again isn't the worst outcome. Yelich' hitting .400, .536, .880, 1.416 over the last 28 games, .370, .508, .804, 1.313, maybe he's that good however, its more probable there's going to be a large regression to the mean. Case in point, Daniel Murphy, 2015, NLCS, hottest hitter in history goes 3 - 20 in the WS. Haven't looked it up because Yelich really stands out but, I suspect there's other Brewer hitters due for a regression to the mean as well. It's going to happen at some point. Given the Cubs on again, off again offense there's also a chance it'll click for a series of course, that means it'll probably go back into the tank for the NLCS.
