Honestly, the way that NBA teams are being constructed these days by having max money available and players essentially working together to orchestrate a roster...I don't see why Phoenix is any worse a destination than anywhere outside of the Lakers, Knicks, Celtics, Bulls, and Heat.
I know we're making fun of golf as a free agent lure here, but golf is just indicative of the weather and lifestyle possibilities open to players if money and endorsements are equal to another contender. Proximity to Southern California and Las Vegas for players hitching rides on jets is something places like Milwaukee don't offer either. The Suns should be worried about their standing with respect to the Clippers and Warriors, though. Both are outside of the first tier only at the fault of their own ownerships.
I don't expect the Suns to be a player for Williams and/or Howard. But at some point if they do get a young all-star, things can fall into place. Unfortuately we probably can't look to the draft for that first piece, just like always...
