I hope the Padres can AT LEAST extend the series, if they can't just win it.
I think the Cubs are the Brewers' biggest threat to making, nay, winning the World Series. I think they are a bad matchup for the Crew because of their elite defense. The Brewers thrive against poor defense. It's why I'm not as concerned about the Dodgers, or even the Phillies (although those teams terrify me, too, but for other reasons).
With that said, I still would favor the Brewers to represent the National League in the World Series, and I would favor them above any American League participant. For the better part of the season, the Brewers have proven their ability to score runs and make life difficult on the best pitchers in baseball.
PREDICTION: I think that the MULTIPLE meltdowns by elite closers in last season's playoffs has taught us that relief pitcher pitch counts matter a lot. The Brewers' ability to get into, and stay into deep counts, will prove a reliable, repeatable skill. And it will make this one of the greatest postseasons in Major League history, with fast-paced, dramatic at-bats, with runners on base, late in games, in which the Brewers come back to win.
