It's definitely regressed, but I don't expect it to last long term.
That said, it doesn't help that Brad puts out one of the most atrocious bench lineups out there for chunks of games, in which the other team scores at will and climbs back into a game, like in the 4th quarter today.
Rozier in particular was wild and didn't seem to try on the defensive end (along with some others). That's how Suns cut a 16 point lead quickly in the 4th.
