 In the 1967 NBA Playoffs , the Sixers yet again battled the Boston Celtics in the Eastern Division Finals , and again held home court advantage . In Game 1 , the Sixers beat Boston 127 – 112 , powered by Hal Greer 's 39 points and Chamberlain 's unofficial quadruple double , with 24 points , 32 rebounds , 13 assists and ( unofficially counted ) 12 blocks . In Game 2 , the Sixers won 107 – 102 in overtime , and player @-@ coach Russell grudgingly praised Chamberlain for intimidating the Celtics into taking low percentage shots from further outside . In Game 3 , Chamberlain grabbed 41 rebounds and helped the Sixers win 115 – 104 . The Celtics prevented a sweep by winning Game 4 with a 121 – 117 victory , but in Game 5 , the Sixers simply overpowered the Celtics 140 – 116 , which effectively ended Boston 's historic run of eight consecutive NBA titles . The Sixers ' center scored 29 points , 36 rebounds and 13 assists and was highly praised by Celtics Russell and K.C. Jones .
