Spears, Globe Staff | September 21, 2007BURLINGTON - With an elusive NBA championship ring serving as motivation, Ray Allen has no problem going from a Sonics star to a Celtics co-star.Allen has averaged 21.5 points during his 11-year career and a career-high 26.4 points last season with Seattle. But now with hot-scoring All-Star teammates Kevin Garnett and Paul Pierce, Allen's scoring average will certainly dip and his spotlight will be shared. But considering he is tired of losing and eager for a realistic shot at a title in Boston, the seven-time All-Star has no problem being a star among stars."I've never been insecure," Allen said after a media luncheon for Comcast SportsNet yesterday. "I've never been the jealous type. I don't have a big ego. But I have a lot of bite. I have a lot of dog inside of me. When I need to go and do what I need to do and get what I need to get, then I'm going to do it. As far as other people, I celebrate other people's careers because it makes me work harder.</div>Link
