Who coached Celtics to 2008 title?

Today’s question: When the Boston Celtics won the NBA Championship in 2008, who was their coach?

Yesterday’s question and answer: The 1968 Olympic gold medallist in the Heavyweight division was George Foreman, who entered the 1970s with a perfect 13-0 professional record, mostly against unknown fighters. In August of 1970 he fought his first world top-ten ranked boxer, who he knocked out in the third round. Who was it? The answer: George Chuvalo: Chuvalo was a highly experienced fighter for the young Foreman to meet so early in his career, particularly when you consider Chuvalo’s reputation for iron-chinned toughness. Foreman was able to land one of his legendary right hooks and began to solidify his reputation as a serious contender.
