Well, prior to 2016, it was not uncommon for opposing fans, primarily Cardinals's fans, to trash talk about the "Century of Losing". Brewers' fans are closer, but don't exactly have a lot of successes to brag about, so their trash talk focuses on the Packers. And be kind to fans of losing teams. It's easy to find a group of people get behind a team like the Yankees, who win every year. But the most dedicated baseball fans in my eyes are the peiople who rally behind teams like the Pirates, who have watched their ownership let MLB stack the odds against them and these fans know they are in for a long season, but get behind their team anyway.
