I remember watching him play at the old Boston Garden. He was even more impressive in person then on video. For the record - He was not the only great player on the Celtics team during that period, but he was the greatest of them all. RIP big guy.
Thats sad RIP Bill.. Eerie, I was watching game 6 of the 1981 NBA finals where the Celtics won just last week.. He was the color commentator during the finals.
He played for 13 years and won 11 titles! Also, His team won 2 NCAA championships while he was in college. For the last two Celtics championship seasons he played in he was also the coach!
