I agree, some have said the Phillies are, but their bullpen is bottom third in baseball by most every metric, they lost their best pitcher for the year and while Schwarbs is having a career year, their lineup is aging and much like the Cubs lineup has been prone to some prolonged hitting droughts. Once could argue they are the favorite - but powerhouse....I don't think so.
The Dodgers bullpen is horrific and they have some still good but aging every day talent as well. And the Brewers - I don't think anyone understands how they are doing it but until they do it in the post season I don't think they'll be considered a powerhouse or anything of the sort.
