Problem is what free agent coming to OKC? They were lucky to get PG13.
they don't even need to worry about free agency when they got enough picks to make any team in the league reconsider even letting players get there.
the way teams are always worried about losing players for nothing - okc can just post up and wait. whether its sabonis, derrick white, or some other breakout player that a team isn't in a position to negotiate with beyond a certain point.
meanwhile they've had essentially 5 years to grow organically without pressure on FO, coaches, or their core guys.
