NEW YORK -- The NBA is taking steps to cut down on pregame handshakes and rituals that have become popular with players in recent years. Starting this season, as soon as player introductions are finished, there will be 90 seconds put on the game clock, and teams will be expected to be ready for tipoff after that time.

The guideline will eliminate or severely cut down on the routines that players from most teams go through before games, which often include a series of handshakes with their own teammates before greeting opponents. It also could legislate out individual rituals like LeBron James' famous chalk toss, which he abandoned last season during the playoffs, though James said he'll try to get it done in the limited time.

"I won't change it, I'll be able to work it in," James said. "We'll figure it out."

Over the years, as the elaborate handshakes and other routines have become extended -- for example, Shaquille O'Neal famously created teamwide skits acted out before Phoenix Suns games three seasons ago -- games have routinely taken five minutes or longer to begin after the starting lineups were announced. The NBA is attempting to speed up the start of games.
