Not to be difficult but I truly believe that the Alpha and the go-to scorer will be two different people.
I fully believe that De'aaron Fox has the clutch-gene and has no fear to take the last shot, (for 2). Yet, I do not believe he will be the team's leading scorer. I think that player will be Buddy Hield.
I believe we will have extremely balanced scoring like the team did last year. Last season, six players averaged double figures. Last years per 36 figures showed that Zach Randolph would average 20 ppg. I do not see Randolph getting 36 mpg. But Buddy Hield, who might get close to 36 mpg this season averaged 19 PPG per 36 minutes with fantastic splits of 45/43/87 indicating the man should get more shots and more minutes.
I believe buddy will average 20 PPG, Fox will be around 17 PPG, Bogdan will average around 15, and three or four players will average around 11 to 13. After that the numbers will drop tremendously.
TL;DR - Fox will be the alpha and the guy with the ball in his hands with the game on the line but Buddy Hield will be the leading scorer.
