Also, I think the Miami vs Dallas comparison is a bit misleading.
Dallas was carried to victory by a superstar having a transcendent playoff run. I do not think that Phoenix has any player capable of putting together that type of run in the playoffs.
Some things that Phoenix does do well that scares me though as their opponent is,
Their ability to put the ball on the floor positions 1-4
very good rebounding tandem in Bynum and Odom
4 key players that have done it before in the playoffs and in big games.
