No, not really. The bottom 5 teams in offensive efficiency are 76ers, Magic, Mavericks, Hawks and Grizzlies. They are ranked 5th, 6th, 12th, 15th and 22nd in assist percentage.
It's always going to come down to context with individual teams as well, the players they have, etc, and particularly with poor shooting teams such as the Sixers and Magic, assists don't do a lot of good when they don't convert at a high rate. Doesn't matter if you assist 100% of your baskets if you shoot 30% as a team.
That's why I said "pretty high" and not "extremely high", but maybe "pretty high" was even an overstatement.
I think the main complaint here stems not just for the sheer fact that we have an absurdly low assist rate, but that the primary culprit is that we just don't always have a lot of ball movement in general, and people don't like watching a lot of iso play and would like to seem more unselfish team ball and that it would be nice to see more people involved in the offense every night, rather than people taking turns on stepping up while some other players often at times do a lot of watching. I think the feel is that with more team ball players and chemistry would develop faster which would down the road likely lead to more wins.
I believe that we would need more of a historical study to determine the correlation between assist percentage and Offensive Rating (points scored per possession); one quarter of one season is not necessarily going to tell us much. Generally speaking, an assisted field goal is going to be much easier than an unassisted field goal, and thus assisted field goals are more likely to produce an efficient field goal percentage. However, more assists can also yield more turnovers. One also needs to conjure with the quality of a team's self-created field goal attempts and self-created scorers, as that caliber can vary widely. Moreover, players who can successfully create their field goal attempts are also more likely to reach the free throw line. Statistically speaking, assists possess no direct relationship to free throw attempts, even if assist-like passes often spawn free throw attempts, so that factor also must be considered. And then once needs to consider a team's caliber of three-point shooting, whether of the self-created or assisted variety. So there are many factors—many spokes in the wheel—that potentially determine an offense's efficiency. (Offensive rebounding could be another.)
What is true is that in the abstract, or as an isolated factor, assists probably do not bear a consistent relationship with Offensive Rating. However, assists in conjunction with other positive elements probably constitute a major difference maker, hence Golden State's stunning success right now. The Warriors move the ball and facilitate many catch-and-shoot looks, yet Golden State also features two of the NBA's best players at creating their own shot, Stephen Curry and Kevin Durant. Or consider the Suns in '92-'93 and '93-'94, when Phoenix led the NBA in Offensive Rating. The Suns featured two players, in Charles Barkley and Kevin Johnson, who ranked among the best passers at their respective positions. Those two players also excelled at creating their own shots, drawing multiple defenders, and reaching the free throw line at high volumes. Additionally, the Suns possessed other good passers, good catch-and-shoot three-point shooters, and good assisted finishers who understood their roles and did not generally try to do too much. Those Phoenix teams really covered all the offensive bases.
A quick look at the NBA in '88-'89 is potentially revealing. The top two teams in Offensive Rating were the Lakers (113.8 points scored per 100 possessions) and the Suns (113.1 points scored per 100 possessions). Meanwhile, Los Angeles tied (with Denver) for second in assists per game at 27.83, following by Phoenix at 27.80. The Nuggets' Offensive Rating, however, was about average, thirteenth out of twenty-five clubs and 108.6, compared to the league mean of 107.8. And the league leader in assists was the first-year expansion Charlotte Hornets (the original Charlotte Hornets), who finished just twenty-first among twenty-five teams in Offensive Rating at 103.7. Like most first-year expansion clubs, or like Philadelphia now, the Hornets lacked for All-Star-caliber individual scorers, so they needed to assist each other in order to score—their abundance of assists suggested their lack of actual talent. Thus, in that sort of case, assists can be misleading. But clearly they were not misleading in the case of the Lakers and Suns, who posted the two best records in the Western Conference with 57 and 55 wins, respectively, and blew through the first two rounds of the Western Conference Playoffs (the Lakers going 7-0, the Suns going 7-1) before meeting in the Western Conference Finals. In addition to plenty of assisting and excellent ball movement, though, the Lakers and Suns both featured a player who excelled at creating his own field goal attempts and at reaching the free throw line: Magic Johnson and Kevin Johnson, respectively. And those clubs featured other players who could create their own shots, such as James Worthy and Tom Chambers, although those guys would not have been nearly as efficient without Magic Johnson and Kevin Johnson. Yet that combination of ball movement plus players who could excel at creating their own shot is probably what separated the Lakers and Suns. The Nuggets possessed some of that self-created element in addition to their assists, but not to the same extent. Thus Denver proved average offensively. The Hornets, conversely, seriously lacked that self-created element and thus constituted one of the most inefficient offensive teams in the NBA despite their league-leading assists average.
By the same token, featuring the NBA's best at creating his own shot will not, by itself, translate to an especially efficient offense. Indeed, Michael Jordan's Chicago Bulls in '88-'89 ranked twelfth in Offensive Rating at 109.1, just ahead of Denver. The Bulls placed sixth in assists average that season, but their team leader in assists by far was Jordan himself. But when Phil Jackson took over as Chicago's head coach the following year, '89-'90, and instituted the triangle offense in part to improve the Bulls' ball movement and balance, the Bulls improved to fifth in Offensive Rating at 112.3. (The Lakers again led the league in '89-'90, this time at 114.0, while Phoenix finished third at 113.1. However, while the Suns ranked seventh in assists average and the Bulls eighth, the Lakers fell all the way to eighteenth. Thus, again, the relationship between assists and Offensive Rating is unclear at best.)
Assists are ideal, I would say, but interpreted in isolation, no one element will be that revealing or possess a direct bearing on offensive efficiency. As for the current Suns, though, their lack of assists (worst in the NBA) clearly represents a problem because the team's Offensive Rating is poor (twenty-third of thirty). Thus their self-created scoring opportunities are not that fruitful—Toronto gets away with a lack of assists (twenty-fifth right now in assists average), because the Raptors feature two guards who excel at creating their own offense, with one (Kyle Lowry) excelling at creating and converting his own three-point field goal attempts (7.0 per game total at a .422 clip) and the other (DeMar DeRozan) excelling at creating and converting his own free throw attempts (8.9 per game total at a .833 clip).
The Suns do not feature those kinds of players, try as some of their guards might, so their lack of assists indeed constitute a negative defect. Brandon Knight can create his own shot, but his conversion percentage is obviously poor. Eric Bledsoe can reach the rim, but his jump shot is impure and unreliable. Devin Booker might one day be very good at all of this stuff, but right now he is still feeling his way and learning the art of discretion.
In short, not every team needs a lot of assists to be efficient offensively, but the Suns need a lot more than they are currently recording.
