For what it's worth, I do think that the Suns will pick up one or two inexpensive free agents this summer. Langhi is likely gone. Ford is gone. Brown is gone. Williams is gone if the Suns can find a better option, which I hope they can, because Williams can't get it done anymore.
I'd like to see the Suns draft either a PF or a swingman. All of the decent center prospects will be gone by the time the Suns pick. The Suns need a backup PG, but they've done a good job finding free agent PGs on the cheap in recent years. It's harder to find backups at PF or SF/SG. Right now, Stoudemire is basically backed up by Outlaw, but Outlaw has only two more years on his contract and will soon be trade bait (if he isn't already). Similarly, Marion has really no backup at all, unless you count Johnson, who is still supposed to be the starting SG of the future. A combo forward might be the best option of all.
So I see, hopefully, this kind of team next year:
C - Tsakalidis (if he plays)/Voskuhl/Williams-Campbell-(Outlaw)-FA?
PF - Stoudemire/Outlaw/#17
SF - Marion/Johnson/#17
SG - Hardaway/Johnson/Jacobsen (I guess)
PG - Marbury/Hardaway/FA
Unless I've miscounted, that's twelve players. Oh, I left out Gugliotta. I guess that one of the guards (Jacobsen or the third PG) will have back spasms until someone gets genuinely hurt.
I'm guessing that the Suns will still try to find a way to buy out Gugliotta's contract. Even if they have to pay him $10 million, it's probably worth it. (What is he going to make next season, something like $11.5 million?) The contribution he makes will be so close to zero, it's worth saving any amount of money not to have to worry about him anymore.
