The Evolution of Elite Defense in the NBA

You got to be a top 10 defense to win the NBA title. It's some sort of law. They look like they're going to be the first team to really violate that rule in a long time. I've been really skeptical of them even in this last few years because their playoff defense hasn't been very good. What did you see last night from Boston and or from Miami that should give the people. any belief that the Celtics could break the 150 team losing streak of teams that are down 0 3 in series?
