It was a mindset in all of the timeouts to continue to attack and play aggressively.”The Badgers scored 42 points in the paint and made 10 3-pointers.”It shows how dynamic we are and the confidence we have in each other,” said John Blackwell, who had 24 points and 10 rebounds. “It shows that we can score without threes, play great defense and get transition buckets. We just have to keep doing it.”
