As I watched the game against the Mavs, I was thinking the same thing. Holiday would be a PERFECT point guard for this team. Trading for Holiday could be tricky, as he makes around 26M if I remember correctly. With Ariza, Chandler, Arthur, and Rivers bought out, the Suns are thin on contracts, unless someone is willing to take Anderson. Jackson, Bender, Daniels combine for about $14M. Warren would likely need to be included due to his 11.7M contract. I think the Suns would have to send close to $20M back, and I don't see how they can get it done. I am not sure if a draft pick counts as "salary."
Basically, I'd offer our pick, Bucks pick, JJ, Bender and Daniels as expiring contracts, and I am guessing that Warren would need to be included. They can also wait until the offseason and do a sigh and trade involving Oubre. Or hell, they might take Anderson with enough picks?
