Brandon Ingram is a first option but CJ McCollum has been gaining traction, swapped Hardaway and a few seconds for him they'll more than recoup in other trades. KJ Martin's recently been sidelined with a foot injury and the Sixers are looking at Simone Fontecchio among others. Martin, McCollum, and Gary Harris all expire after next season, helping Detroit's likelihood to extend Jaden Ivey and Jalen Duren while maintaining potential free agency and draft signings under the new CBA.
Second round picks generally are valuable not just for developing project players overtime or taking a day one surprise contributor, but the Pistons have enough in their arsenal to trade up into the first round, earlier in the second round, or trade back/out entirely with less overall drawbacks. Picking up role players to best surround their more central talent is their inevitable step forward. This is that step.
