Walton was great because his skills and fundamentals were an ideal fit for a position that no longer exists in the NBA: a back-to-the-basket center with the height to receive a pass into the post, the vision to distribute to both cutters and spot-up perimeter shooters, and the quickness to spin to the basket either right or left and finish at the rim.
I recall that Blazers team so well without even consulting reference materials: a great center in Walton, perhaps the league's most intimidating enforcer of all time in Maurice Lucas (but he was more than thug; in fact a weapon at both ends), blinding speed in the backcourt with Lionel Hollins and Johnny Davis, and a jack-of-all trades wing in Bobby Gross. Th construction of the lineup was prototypical for the NBA during that pre-Showtime era. The Sixers team they played in the finals had been the sexy pick all season with offensive powerhouses at forward in Julius Erving & George McGinnis, plus Doug Collins (potential HOF skills if he had stayed healthy), but Caldwell Jones at center and Henry Bibby at the point were both limited and posed little offensive threat. Erving and McGinnis did not complement each other, and it didn't help that McGinnis shot something like 33% over the first five games while taking the second most shots after Erving before finally waking up and having a good game 6. With very little production apart from Erving & McGinnis in game 6, the Blazers closed the out the title 4-2 with a balanced attack (all five starters scored in double figures).
