Schroeder has a checkered history, to put it mildly, and even as the loudest voice against getting Payton, I still was not keen on bringing in Schroeder, because while Payton is awful, at least Payton wasn't a toxic quitter.
I still don't think Payton is toxic but he does seem to have given up, at the very least he has regressed from being 'very sub par reserve' level bad to 'Is he the worst player in the NBA?' level.
At this point Schroeder may represent the better of 2 (IMO) lousy options. At least Schroeder has some boom potential, while all Payton is giving us is a dumpster fire.
If all Schroeder cost us was Smith... I would be behind it right now. Payton has been a lousy player his whole career but this recent stretch is on another level, he is unusable, a turnover machine who can't hit a shot to save his life and his defensive mindset seems to be to gamble for steals while totally ignoring his assignment.
I would still prefer us just flat out cutting Payton and offering someone from the G-League or some other scrap heap a 10 day "prove it" contract over giving up anything for Schroeder, but... we HAVE to do something, especially if Cam Payne is out for more than another couple games. And even then, we need a serviceable 5th guard regardless.
