The truth of 2003 is plain and simple: the Cubs choked. They didn't need any special excuse; blowing a two run lead in game 7 confirmed that. And let's not forget, they could have clinched in game 5, but got shut out.
That said, I'm a White Sox fan that lived on Waveland Ave just down from Wrigley for 12 years. I watched a LOT of bad Cubs baseball, while listening to the Cubs fans who continued to fill the stadium and make excuse after excuse for the team. The night of the Bartman game, as a neighborhood resident with my windows open that night, hearing the sound of the stadium and my neighbors watching tv, I got sucked in and found myself actually rooting for the hometown team. Then they choked, which reminded my why I never rooted for them. In a wave of neighborhood vandalism after the game, the side view mirror was ripped off my car . Admittedly, I've carried a special grudge since.
Fast forward to last season - I'm living in a different neighborhood. A few blocks from me, a homeless guy had been living for months in a shelter he made under the El tracks. He never panhandled or bothered anyone, but he was dirty, smelled, and was clearly suffering from alcoholism and depression. The morning after the Cubs finally won their first game in the series, I walked past him on my way to grab a cup of coffee. There he was smiling,donning a brand new Cubs, dancing, and singing to himself "Go Cubs Go". I had never seen him happy. And I thought to myself, If the Cubs winning the World Series can bring some joy to this guy's life, I'll pull for them.
If it brings joy to your life, enjoy the Cub's championship. I hope it brings you a
lifetime of memories.
