Colangelo could screw it up but so far he has been Hinkiesque. The only guaranteed multiyear contract he gave last year was Bayless (3yr/27M). He got a 1st for trading Grant for Ilyasova. Then when Saric improved and Ilyasova indicated he was looking for a multiyear deal he dumped Ilyasova for a 2nd.
This offseason I think Embiid's and Simmon's injuries should keep Colangelo from screwing up too badly. If they should stay healthy and make (or get close to ) the playoffs this next season, I could see Colangelo making bad moves to rush the process and end up screwing up their chance to be a true contender. However if Embiid can stay healthy, he'll be so dominant I'm not sure even Colangelo could screw it up.
