Either wait a year or two and then soft rebuild after Horford is gone and Hayward is closer to expiring, the danger there is by that time you will have had to pay the young guys and may not have as much cap flexibility. A big part of their window was having guys like Jaylen, Jayson, Smart, Rozier, etc... on cheap deals and salary cap space to put stars around them, it's just that those stars ended up being Hayward and Kyrie.
The other option if Kyrie walks is to bring back Horford and use some of your secondary pieces and picks for a Holiday or Conley type.
