I dislike the every other day game schedule for the NLDS, which should pretty much keep bullpens on really good rest throughout - Kind of wish they wouldn't have planned off days between games 1-2 and 3-4, as it would preserve some of the strain the Cubs' pitching staff put on themselves during the 3 wildcard games.
That being said, these off days between games will give the Brewers' key pen arms all the rest they need to be available every single game, too. The mix of Ashby, Koenig, Uribe, and Megill being able to go rinse/repeat for 5+ innings each playoff game as needed without much of any worry on rest is pretty damn solid.
As has been the case with other Brewers' postseason runs, how far they go will most certainly depend on how many runs they can consistently score. At some point even the most airtight pitching staffs spring postseason leaks, and teams that win titles take advantage.
