I think everyone wants their team to be playing elite baseball when it matters. I agree the cubs haven’t in a couple months. But the brewers doing it in July/August is also not indicative of them doing it in October.
Teams play above and below their true talent level over the course of a six month season. Throwing out their very good stretch because it isn’t historically sustainable while taking their play since then as gospel isn’t a fair way to evaluate the team. The team killed it offensively for two months, and then…fill in your own adjectives since then about the offense, but as frustrating as it was, they played at an 85 win pace. Is it the 2016 cubs? No. Is it decidedly worse than the rest of their competition this year? Also very much no. They’ve punched their ticket to have a shot in October, baseball playoffs are a dumb crapshoot and they will probably lose because every team will probably lose. It’s still a 90+ win team.
