In his second season, Unseld scored a career-best 16.2 ppg. His rebounding numbers remained impressive, and it became clear that he contributed in ways that didn't show up in the box score. He set solid picks, grabbed rebounds, whipped outlet passes to trigger fast breaks, and consistently prevented opposing centers from establishing position in the lane. His 16.7 rebounds per game earned him second place in the league's rebounding race again, this time to San Diego's Hayes. The Bullets were solid in 1969-70, running up a 50-32 record and claiming third place in the Eastern Division.
The NBA realigned for the 1970-71 season, creating two conferences and four divisions. The Bullets were moved to the Central Division, where they ran off five consecutive division les, although their record fluctuated wildly. (They were as bad as 38-44 in 1971-72 and as good as 60-22 in 1974-75.)
During those years Unseld carved out his reputation in the paint. He ranked second in the league in rebounding in each of his first four seasons, slipped to fifth one year, had a down year due to injury, then claimed the rebounding le in 1974-75. He was an All-Star five times during that stretch, despite doing most of his work against players who were much taller, including 7-footers Chamberlain and Kareem Abdul-Jabbar.
Unseld was listed at 6-7, but after he retired, he admitted that he actually had been just a hair under 6-6 all along. However, what Unseld lacked in height, he made up for with his powerful 245-pound frame and sheer determination.
"I know that night in and night out the guy I play against will have more physical ability," he told the Washington Post. "But I feel like if I go out against a guy and play him 40 or 48 minutes a game or whatever, toe to toe, head to head, he is going to get tired or beat up or bored for two or three minutes. That will be enough to make sure he doesn't win the game for his team."
For all his might, Unseld also had great hands, both for grabbing a rebound and for delivering a pass. And, as former Bullets General Manager Bob Ferry told the Washington Post, "He has great anticipation and imagination. He can see something develop, and he gets the pass there at the right time." In addition, while he was not fast, he was very quick, an attribute that was made even more deceptive because of his massive body.
