I'm not really sure what your point is here though. A single series is a tiny sample size where any result would not be surpising. The Brewers could sweep, the Phillies could sweep, or anything in between. It's reasonable to point out that they also have 2 good pitchers and a MUCH better offense.
Of course the Brewers won already, but just like someone could lose 2 football games in the regular season to a team but beat them in the playoffs, it's entirely possible that the Brewers could lose to the Phillies, so we don't need to act like any side of this argument is inconceivable.
