KD had the narrative going for him in the past two years as well before the injury he had in January each year
Kyrie was missing every game for over half the year 2 years ago because of covid while Harden was playing bad and then got traded to the Sixers. Last year Kyrie also missed a bunch of games with the suspension from the Nets, and Simmons who was the main piece they got in the Harden trade was also hurt missing tons of games and even when he did play he was useless. Despite that both years they had a great record by January and were a top-3 seed before KD got hurt and they dropped a bunch of seeding
When KD and Booker are both playing the Suns have played through KD at the end of games. Mavs game last year he got the last shot and hit the game winner. Jazz game this year he got the last shot and hit the dagger. Second Jazz 2OT game they played through him drawing an instant double everytime in late 4th and both OT’s, getting open 3 after open 3. That’s a first option
