I like the idea of PG as expiring in theory, but there aren't a lot of white whales on the horizon.
The best guys most likely to be available are second tier stars like Mitchell, Murray, Zion, Fox... guys who are all carrying similar conditions to those that made us want to move JB.
There is the chance that the LaMelo experiment goes horribly awry in Minny, which combined with an aging Gobert, makes Edwards want out. But a guy like that will require more than cap relief and future picks.
