I think whatever the approach is it has to be decisive. Plan A should be to go after Davis, get him and Kyrie looks better as the number two guy. Beyond that there is certainly stuff you have to figure like what to do with Hayward but getting the top 10 player has to be the first play. I do however have a limit, I'm not including both Tatum and Brown. This is in part because of how bad Hayward has looked in general this season, you can't give up both of your young wings on the HOPE that Hayward is better next year, because theres a chance he just isnt and never will be. And without him you arent good enough with just Kyrie and Davis.
If you can't or don't get Davis blow it up. That includes letting Kyrie walk, seeing if we can off load Hayward, and if that means Horford goes he goes. Force feed the young guys, use the draft picks on high upside guys and reset this. Because if you don't a big star this summer than all of a sudden Jaylen is up for an extension next summer, Horford is entering his age 33 year, Hayward may never be all star level again and most of your draft pick capital is now used (except for hopefully the MEM pick). Meaning that our avenues for getting another star through draft or trade have essentially expired. Force feed the young guys, see if they can be more than they were this year.
