Of course this is a must-win game for the Cubs. Going down 3-0 is pretty much the end of this thing. Not that already being down 2-0 is a walk in the park.
Since the LCS went to a best-of-seven format, there have been 60 teams to drop the first two games. Only thrice has one of those teams come back to win and advance to the World Series.
Two of those three times were in 1985, as both the Royals and Cardinals lost the first two games on the road before advancing to the WS that year.
What else happened in 1985? Marty McFly hopped in his DeLorean and came to the year 2015 and saw that the Cubs won the World Series.
I still believe the Cubs will win the WS this year. Because if they don’t, that means movies aren’t real, and I refuse to live in such a world.
