Philly needed a shooter and traded Richardson and a pick for Curry. OKC received a potential first round 2021 pick and a 15 million dollar trade exception for Oubre. Phoenix got Chris Paul for Rubio and Oubre, and then OKC got the 17th pick in the draft for him. In short, 23 and Davis doesn’t get us any of those players, not to mention the money is nowhere close to matching for any of them.
Also, unless everyone knows something I don’t, why is everyone so confident Udoka would have been available at 38 or 39? If the Jazz were confident of that don’t you think they would have? They either would rather have him on a rookie deal for 4 years instead of 2, had reason to believe someone else was going draft him between 27 and 38, or both.
