By many measures, the Phoenix Suns as a team appear to have reached their peak. They first tied a 53-year franchise record for playoff wins (14, in 2021), and followed that up with a franchise record in regular season wins (64, in 2021-22) before that playoff flameout that no one can properly explain, even their opponent.
The Suns may have reached that peak, and the only direction from here could be down. But we don’t know that for sure, because sometimes the next peak is only visible after you’ve reached the current one.
The Suns may have a lot further to climb, but for that to be true we will have to see some dramatic internal improvement from some of these guys.
