If a win streak before the all-star break doesn't matter, why should a lose streak matter? You guys were all going nuts during the 6-game lose streak... does it not matter? Something's not symmetrical here.
Losing streaks are always tough. But, if you're talking less than 10 games before the all-star break, and there aren't multiples of them (as in one really bad stretch), and aside from the streak the team looks good, they usually don't matter.
The trick is to figure out the true pattern from the outliers.
