In reality regular season means nothing at this point. Any team can get hot and go on a heater. When it comes down to it Kershaw isn't his dominate self in the playoffs, Wood started to struggle could be a bit to many innings for him and Darvish didn't look unhittable when he came over. Again though anyone of those pitchers could get hot in a second.
This is anyones series these two teams aren't that far off. If you wanna throw regular season numbers out there. Cubs were barely .500 in the middle of the season and ended up with 92 wins.
