The way I see it, go all in on right now. We do our best by Gobert and Ingles to put the best team possible around them.
Trade Rubio and Niang for Jabari (I would want something else minor in return)
then
Trade Favors for Hardaway and Ntilikina
For this season and next, we have the following guys under contract:
Gobert
Donovan
Ingles
Hardaway
Jabari (if we want to bring him back next year)
Korver
Crowder
Ntilikina
Exum
Royce
Allen
Bradley
After next season, Korver retires and we make a decision on Crowder, Royce, Bradley and maybe Jabari.
So through Mitchell's rookie deal, we do our best by the aging roster that we have. Once Mitchell goes to sign a new contract in 2021, we have cap space to go in a new, younger direction led by him. By that time, Hardaway, Ingles, Gobert, Korver, Crowder, Jabari and Crowder are gone or are unrestricted free agents. And maybe we have proven to be a better, more attractive franchise that can attract another big fish or two to join Mitchell.
