I don't think you can say it doesn't effect them, but I think it's minimal. While not a crapshoot nor an absolute certainty, the Cubs Head to Head lines up 3,4,5 against the Brewers at end of July, 2,3,4 in early September and 3,4,5,1 in late September. So 3 starts? And only see Arrietta and Lester once a piece. I'm not wringing my hands over this. The Brewers have the 3rd easiest schedule, statistically speaking in MLB the 2nd half. Just beat who you should beat, go .500 against the Cubs and Cardinals and make the Cubs play .620 ball over the final 70 games. Quintana doesn't change much with what the Brewers have to do.
