Thinking Basketball put out a Youtube article talking about the trend towards 'heliocentric' offenses, where more and more teams are utilizing one feature 'star' who quarterbacks as much as 50% or more of the offensive load (through a combination of both scoring and playmaking).
https://www.youtube.com/watch?v=r0934lGZ4dwThe obvious exemplars for this are guys like veterans Harden & Lebron and you have relative new guys like Giannis and Doncic. Kyrie, when healthy, plays at just barely under the 50% offensive load mark.
The model represents a move away from having multiple play-making scorers and is a product first of the expansion that happened a while back and then the rising importance of the 3PT shot resulting in a more open floor and making it easier to keep initiating offense through the same perimeter player.
The Celtics obviously relied on this model as well in recent years, first with Isaiah and then with Kyrie. And Kemba himself was clearly "that guy" while in Charlotte.
I find it interesting, though, that the Celtics have moved very deliberately away from that model, taking advantage of the return of Hayward and the emergence of The Two Jays' improved play-making skills to distribute play-making as well as scoring through multiple players on the floor. And this isn't just with the starters, as Brad routinely initiates offense with Smart, Wanamaker and even the rookies. He'll even let those bench guys initiate the offense while Kemba or the other starters are on the floor.
Kemba is still our highest usage guy and chief playmaker, but being under 29% USG and under 28% AST% he's a distinct step back from the load-hogs like Harden & Co. And Kemba seems to slide smoothly and happily into secondary or even tertiary roles in the offense. I.E., those raw numbers don't reflect how in one game, yes, he'll be The Guy, carrying 50%+ of the offensive load and then in the next one, he'll slide into the background, cheering on Jayson & Jaylen.
Jayson and Jaylen are both posting career highs in assists and it's no longer anomalous when one of them dishes out 4-5 dimes in a game.
When Danny signed Gordon Hayward to come and join Isaiah and Al, I think that even back then they were trying to move to a roster that could support using multiple players carrying the offensive load. Obviously, Isaiah's hip injury (and subsequent trade for Kyrie) and Gordon's foot injury completely disrupted that. And Kyrie never seemed quite the good fit for that idea.
Even going back to when Brad first arrived, he tried to use guys like Jeff Green and Evan Turner as point-forwards to spread the way the offense was initiated, to varying degrees of success.
But now, I think Brad finally has the roster that he needs to make this work.
