That Sixers team was stacked and still lost. Sixers had G 14 Henry Bibby (UCLA) F/C 23 Joe Bryant (La Salle) C/F 42 Harvey Catchings (Hardin-Simmons) G/F 20 Doug Collins (Illinois State) C 53 Darryl Dawkins (Maynard Evans HS,Orlando, FL) G 10 Mike Dunleavy (South Carolina) F/G 6* Julius Erving (UMass) G 21 World B. Free (Guilford College) G/F 25 Terry Furlow (Michigan St.) C/F 11 Caldwell Jones (Albany State) F/C 30 George McGinnis (Indiana) F 50 Steve Mix (Toledo) They lost to the Trailblazer who had F 10 Corky Calhoun (Penn) G 16 Johnny Davis (Dayton) G 3 Herm Gilliam (Purdue) F 30 Bob Gross (Long Beach) G 14* Lionel Hollins (Arizona St.) C 34 Robin Jones (St. Louis) F 20* Maurice Lucas (Marquette) F 36* Lloyd Neal (Tenn St.) F/G 15* Larry Steele (Kentucky) G 13* Dave Twardzik (Old Dom) F 42 Wally Walker (Virginia) C 32* Bill Walton (UCLA) I'd say the Portland Trailblazers were a bunch of no names. I can only say that Maurice Lucas and Bill Walton as the only recognizable names on that team yet they still beat the powerful Sixers.
Of course even in this one example, Portland still had Walton, who was the MVP of the league the following year. So this isn't even that great of a series to make any kind of a case. Walton's numbers for the year - 18.6 ppg, 14.4 rebs (led league), 3.25 blks (led league).
