Dodgers in six.
Realistically, this is the best team they have assembled the team that won the World Series in 88. Revamped bullpen, deep starting pitching (a foursome of Kershaw/Wood/Darvish/Hill looks better than what the Cubs have on paper), a manager that doesn't have rocks for brains and most importantly, a bullpen that isn't a glorified trash heap.
The Cubs are coming in weakened compared to last year (hello, lack of bullpen) and battered considering they're looking at a scenario where they have to start Lackey in game 1 and then Lester on short rest in game 2. The Dodgers can easily make life hell for the Cubs if they can take advantage of that. A Cubs team that wasn't all that impressive in the NLDS to start with.
Bellinger wins the LCS MVP and the Dodgers march to the World Series.
