He shoots! He scores! But who cares? The average rating for the NBA Finals between San Antonio and New Jersey on ABC was 6.5 with a 12 share over six games-the lowest since Nielsen began using its current measurement method 27 years ago. Despite a highly competitive and often exciting series, fans in big cities generally tuned out. Last year’s finals between the Lakers and Nets scored a 10.2 rating, which was considered a disappointment then but looks a lot better now.
