Given the way this division is shaking out, I think the Brewers are clearly the best team in the division, with the caveat at some point their ridiculous number of injuries stop happening. I think the Cubs' best path to the postseason is using this relatively weak division to come in second with 85-ish wins and a Wild Card berth.
But if the Brewers' injuries continue, 85 wins might take the division itself. But Milwaukee has several guys on the mend so that would require a bunch of re-injuries to guys like Miley, Lauer, Adames, and Urias in the short-term and guys like Woodruff in the mid-term.
