As a former point guard, I would love to agree with all these "we need a true point guard" hot takes. But these totally ignore the way the game has evolved at all levels, which is to have multiple initiators and creators on offense. The ACC has had a TOTAL of 6 players average more than 5 assists per game over the past 3 seasons.
This Duke team has 5 players capable of initiating and creating - Cooper, Kon, Tyrese, Caleb and Sion. There are usually at least 3 if not 4 of them on the floor at the same time. But we have been not been taking full advantage of that and have instead been running everything through either Cooper or Kon for long stretches, with the other 3 players often standing around waiting for a kick out or dump off. As good as those guys are, this approach makes us more predictable and easier to defend as a result.
To put it differently, I would much rather see Kon’s role be mix of catch and shoot 3s, curling around screens, driving to the rim and creating for others, rather than serving as the de facto PF for long stretches at a time. And I think Cooper would also benefit from playing off the ball more, and better able to exploit smaller or slower defenders off of ball movement rather than after bringing the ball up court.
