I'd go at it differently.
For one thing, I wouldn't use the word "unacceptable" because whatever happens we'll have to accept it,and move on.
I would say:
5-0: so incredible coming on the heels of the 14 game winning streak that I would really wonder if this is all real
4-1: Exceptional
3-2: Excellent. Pick up a game, win the season series, and leave the Cubs with no more head to head opportunities.
2-3: OK, but missing a chance to put the Cubs in a huge hole.
1-4. Concerned A 5 game lead with 34 games left sounds good, but you don't want to get there by losing 4 games off your lead in 5 days. A reminder that the Brewers hot streak is over and there is a lot of season left.
0-5; Alarm. the appearance of a historic collapse in progress. It would present a major challenge to the confidence shown by this relatively inexperienced team.
As always, win one first then go from there to knock the worst case scenarios off the table.
