It's pretty funny that the Suns are still paying Josh Childress for two more years. Can you imagine if he were still on the roster?
Don't forget Frye. If I remember correctly, Sarver signed Chilli, Frye, Hedo, and Warrick all in one summer- four of the worst signings in recent history.
Turkoglu was a trade (Barbosa), but I take your point. Even so, I always felt that Childress was by far the worst overpayment. Frye was a solid contributor before his heart problem, and Warrick was at least relatively cheap. Childress was clearly awful and the Suns paid him at least three times as much as anyone else would have dreamed of doing.
