My moment was the 2005 AFCDG loss to the Broncos. Like you, I was a Pats fan my whole life, going back to the first Super Bowl loss, then the horribleness of the late-80′s and early-90′s. But when they lost that game in Denver I realized BB/TB had a finite shelf life and they were going to have to build a whole new defense in the process. That’s when I allowed myself to fully invest not only in understanding the personnel and schemes of the team, but to being a fan and allowing myself to actually feel something based on every win and loss.
