PHOENIX — The Lakers punched their ticket to the NBA Finals tonight with a victory over the Phoenix Suns in Game 6 of the Western Conference finals. Kobe Bryant wouldn’t let the Lakers give up all of what had been an 18-point lead, scoring 37 points and prompting Lamar Odom to say, “Kobe is so good he makes incredible seem normal for us.” The Lakers advanced to the Finals for the third consecutive season and for the 31st time in franchise history. They will meet the Boston Celtics for the second time in three years. The Celtics beat the Lakers, 4-2, in 2008. The Lakers beat Orlando, 4-1, last season. The Lakers have won 15 championships; the Celtics have won 17.
