I keep going back and forth on this KD stuff, and I just seem to come back to the fact that the Suns completely collapsed in the playoffs. It was supposed to be (judging from the regular season) a very deep team that had too many weapons to be neutralized. Then they just stopped showing up from roughly three-quarters of the regular season. Even if they retain Ayton and repair whatever the hell happened in the playoffs, how much further can they improve that team? Enough to get through the Mavs? Sure, most likely. Enough to get through the Warriors or Boston? I doubt it.
KD is good enough that Booker becomes your second option, and in my opinion, the Suns are more likely to get through Golden State, Boston, etc with KD than they are if they just roll it back. Assuming KD and Paul stay healthy, that;s a dangerous team, especially if they manage to retain Bridges. I am a bit concerned about their defense if they lose Ayton AND Bridges, but I am still feeling better about that team than I am about rolling it back.
