OKC Fan Sentiment
From what I've gathered, most OKC fans are resistant to the idea of trading some of their players for players of lesser talent and salary cap reduction/flexibility. Historically, however, that is how salary cap flexibility has been achieved.
The counterargument I've seen brought up has been to simply decline Dort and Hart's TOs to achieve balance while also opening up 2 roster spots for their rookies. To that, I give the FA signings above that would directly hurt OKC's ability to win in the regular season and increase difficulty in the playoffs.
