I worked late last night and I don't get to see all the Celtic games, since I live in NY, but based on pure statistics, I think we can sacrifice some interior defense if we can just score more buckets and get to the foul line. When was the last time the Celts topped 100 points? Even against the atrocious Knick defense, they only scored 96. They only gave up 90 points last night and still lost.
Unfortunately, I think our problem is on offense, not defense. A healthy Shaq can help there, but Rondo needs to get aggressive.
