Cody was an incomprehensible one-and-done pick. He didn't show any signs of having Top 10 NBA level talent or physical ability at Colorado. He has some length for his theoretical position, along with name recognition... and that's it.
He was probably picked mostly because his brother is a good player who was kind of a late bloomer. That's an insane gamble to me at #10. Maybe you can justify it when you're some dynasty team that doesn't have to hit on every pick, but the Jazz needed someone who was much farther along.
