Honestly, after 97 wins anything more this season I view as gravy. I figured 85 wins would be a good year though i did expect them to slow play Schwarber and Russell a bit more. Regardless, I feel like the cubs are a team no one really wants to play in the playoffs. From Arrieta and his dominance to the fact that the cubs have handled pressure situations well(13-5 in extras(best in league) and 34-21 in one run games(second to the pirates who were 36-17)), the best road record in baseball, the best(I believe) 2nd half record in baseball and finally the fact they are dealing with a lot of young talent makes for a scary picture.
I suppose you could argue young players are a double edge sword. On one hand they basically are getting better every game but on the other they are still suspect to inexperience. But you do have Maddon who most view as at worst a top 3 manager. And as I said in the opener to this, it's not like this cubs team has much to lose. Think almost any cubs fan views this season a success whether or not they advance. So the pressure isn't really on them where as some teams(say the dodgers for example if the cubs get that far) kind of need this.
