It is fair to question whether trying to rebuild around Lillard is a good idea or not. It is possible that with cap space, tradeable assets, and TPE, that they could quickly get a team around Lillard. Get players like Jerami Grant for example, maybe they find a way to score Sabonis. Maybe Brogdon. Harden, Kyrie, Gordon, Harrison Barnes, Hield, there are players out there. That is a pathway, at least potentially, in theory.
I guess their plan is to try that or at least try that first rather than trading Lillard. There are no guarantees in either case.
