The AP reports: The Rockets hope Ron Artest can do for them what Kevin Garnett and Ray Allen did for Boston last season, forming a trio with Paul Pierce to lead the Celtics to the NBA championship. Boston was the worst team in the Eastern Conference in 2006-07, before Garnett and Allen arrived. “For that team to go from worst to first,” Tracy McGrady said, “that gives me hope.” Yao Ming dismisses comparisons between the threesomes by pointing out the glaring difference. “Boston already got a championship. They can say they have the best three guys,” Yao said. “We are looking for that day. I have that confidence that we can do that.” The Rockets don’t have to make as big of a jump as the Celtics did. Houston went 55-27 in 2007-08, its first season under Rick Adelman, and lost to Utah in the first round of the playoffs for the second straight season.
