I mean I hate to say it as I know Nesmith is still young and maybe he can show improvement just like Grant Williams this season compared to last. But as everyone on this thread is implying, there were a lot of guys to be had that we passed on for Nesmith, and quite a few of them are doing well for their teams and playing key roles in some cases. Bey, Maxey, Anthony, Quickley, etc. And yes, a few guys later like Bane which we could have had for a later pick but traded away.
Unfortunately for this season, Nesmith doesn't even seem to have any role, just a body when someone gets hurt (like Jaylen this past week although Nesmith sadly suffered an injury too). Even in a 9-man rotation, Nesmith would be healthy scratches essentially
