The "if the Brewers just go .500 the rest of the way, then..." scenarios are interesting, mathematically undeniable, and help quantify the value of the cushion. But, as others have mentioned, it is not that uncommon for a team to lose a lead of this size at this time of the year. That can be either because "just going .500" doesn't always happen (remember how the Brewers lost a 5 game lead in the wild card race in virtually no time in 2008 and needed the Mets to collapse the last week just to crawl back in), or because another team puts together the kind of hot streak that seemed so improbable just a month earlier, or some combination of the two. The example I use goes back to 1982. On August 20, the Brewers had a record of 69-50 with a 4 game lead over the Red Sox and a 7.5 game lead over the Orioles (who had a record of 61-57).On that date, you could have said, "If the Brewers just go .500 to get to 92-70, the Red Sox would have to finish 27-18 and the Orioles would have to finish 31-13 just to tie them". The Brewers then won their next 3 games to extend their lead over the Red Sox to 6 games, while the Orioles also won 3 to stay 7.5 back. Those 3 wins by the Orioles were the start of a streak in which the Orioles won 17 of 18 games to cut the Brewers lead to just 3 games with 26 games still to play. The Brewers had won 13 of 19 games (they were not choking) and had seen their 7.5 game lead over the Orioles shrink to 3 games. The Red Sox were also hot and stayed just 4.5 games behind. Over the next two weeks the Orioles got as close as 1 game, trailed by 2 going into the last week, and by 3 going into the historic final weekend when they beat the Brewers 3 in a row before Don Sutton and Robin Yount combined to produce the Brewers first ever division title. The bottom line is that the Orioles, who were 7.5 games behind and with a record only 4 games over .500, amazingly finished the season 33-11 (.750). The Brewers did much better than "just finish .500" (26-17), and they needed every one of those wins to hold off the Orioles. This is just one example, but one that was quite stressful for anyone who was emotionally invested in seeing the Brewers win a division title. So, I consider it more a matter of personal experience, not paranoia, to not take anything for granted and consider every game important until something is mathematically decided.
