It's fine to give that opinion but that says nothing for the type of PG and PF you want to bring in and if there are even any players like that available or not. That's the issue with passing the buck and saying that's the job of management. It leaves you open to say it was the wrong move no matter who is brought in because you envisioned a certain type of player to fill those roles.
You know as well as anyone that there are various types of player at every position in the NBA. Ayton is not a Center the same way that Len is. Channing Frye is not the same type of PF that Barkley was or even Markieff Morris was, if you want to leave past generations players in the past. Even Bender and Chriss were quite different players. You didn't seem to care for either so what type of PF do you want? It's much easier to name a player or two that is in the league that might be available than naming various attributes that apply to some but not other players.
If you want to stop at "management needs to find us a PF and PG" then whoever is brought in to play those roles will be what you asked for since you didn't want to be more specific.
I'll give it a try.
For a point guard, as I have stated before, a steady veteran who is a solid distributor and facilitator, who is at least an average defender, and who has a good enough outside shot to keep opposing defenses honest. Example from Suns history of this type: Kevin Johnson. Lesser example: 2013 Goran Dragic.
For a power forward, tenacious banger, rim protector, reasonably athletic and/or bulky enough to defend opposing power forwards straight up, and at least enough of a mid-range jumper (if not a three pointer) to keep opposing defenses honest. Examples from Suns history of this type: A.C. Green, Wayman Tisdale, Clifford Robinson, Antonio McDyess.
Doesn't necessarily need to be a superstar at either position, but at least needs to be a good, solid veteran core contributor.
