It is widely understood that in the NBA teams need a minimum of two stars to be playoff competitive, and three to have the talent to be true championship contenders.
Obviously the Suns have the first part of the competitive formula with Devin Booker, and they hope that they will at least have one more between Josh Jackson and Deandre Ayton.
However, if either one of them do develop, they likely won’t be ready this season, and might need a least one more year of seasoning before they are ready to help carry the team.
