Jerseys and Personnel are separate issues, with the flat cap issues 3/4 of the league are having the earliest anything is happening is on or near trade deadline.
As for the jerseys, teams can't just whip them out whenever they want it's months of work and league approval, this jersey was decided as coming back MONTHS before this "disastrous" stretch, spin it all you want for all I care this jersey was coming back if we were in the hunt, or the worst team in league history. But it fits your narrative so I get it.
