To be honest, I believe that in the 2014 NBA finals, MIAMI HEATS were not very focus on defense. Generally they let SAN ANTONIO SPURS do whatever they wanted on the floor without trying to cut their rhythm. The only game that HEAT show us a different face was on the second game and its not coincidence that it was the one and only game that SPURS scored under 100 points (110-96-111-107-104) and the one and only that HEAT won. So in that game HEAT were switching a lot on the screens and they were making a lot of defensive adjustments. A small sample of these you can watch on the following video.
