Wow unless injuries hit them hard they just won a world series.
There is a significant degree of luck involved, even taking out injuries, aces can have bad nights(see: Cliff Lee game 1 of 2010 WS) and mediocre pitchers can have good nights(see Jamie Moyer and Joe Blanton in 2008). Increased chances for sure but the "best team" fairly regularly doesn't win it all.
Also I pretty much hate every team in the northeast now, all they do is spend spend spend.
