The Golden State Warriors have probably been the top defensive team in the NBA this season, but the Utah Jazz are throwing that into question and could end the season with the title of most improved. Consistency meets flavor of the month Saturday night when the Jazz head to Oakland, where the wild card might be that it's rarely mattered who the Warriors are up against at home. The Warriors (55-13), tied with the 1991-92 club for the second-most wins in franchise history, lead the NBA with 97.6 points allowed per 100 possessions. The stingy scoring average is better than next-best Indiana by 10.0 points, and the Jazz's season mark of 94.7 is now the best in the league.
