Just watched the condensed version of the Cub's world series win, which is much easier to watch when you know the outcome. :)
Three things jump out. First is that Schwarber hit 3 for 5, had a stolen base, and got the big first hit at the top of the tenth. He had a huge role in this series coming back from injury, despite only playing in Cleveland.
Second is that the Cubs got three runs simply with good base running. It's the little things done well that often distinguish great teams.
Finally, Chapman's performance at the bottom of the 9th after giving up the tying runs in the 8th inning was clutch. He clearly did not have his best stuff, and after blowing the lead it would be so easy to give in emotionally, but he gutted it out, kept the Indians scoreless, and gave his team the chance to win. The script was ready for the Indians and Chapman shut the door.
Chapman factored big in each one of the Cub's victories, and I really don't think they win it without him. If it were up to me, I would have given the MVP to Chapman.
