I've repeatedly said that I'd prefer to trade Isaiah more than Bradley. My points, before the usual suspects call me a hater:
We'd get more return for Isaiah in a trade, presumably. He's the second top scorer.
Bradley will ask less money for his next contract, maybe in the range of 7-10 million per year.
Offense wins games, defense wins championships. We need Bradley to guard Curry/Klay/Kyrie.
Bradley has improved every year and has never spoken out loud after losses in good or bad seasons. Good spirit, Celtic culture, veteran inspiration for youngsters.
He is able to play PG in defense and SG in offense, giving versatility to our backcourt.
So, for me, I wouldn't trade Bradley for Randle. It's a keeper except a very big fish is on the table.
