Steve Kerr supports shortening NBA preseason "I kind of like the idea that's been tossed around the last couple summers to start the regular season a little earlier, maybe a week early," Kerr said Thursday afternoon after Warriors practice. Last October, NBA commissioner Adam Silver told USA Today that the league is inching closer to reducing the number of preseason games. With most players staying in shape year-round these days, many teams see little need for a four-week acclimation period before the regular season. "The starters will be ready to play 30-plus minutes" in the regular season.
