After signing Hayward by trading away Bradley for draft picks do a sign and trade of KO for Tyson Chandler.
He'll be 35 in October, has two years left on his deal, has never had any appreciable level of skill, and has always been a punk (well, at least imo, anyway). Pass.
No appreciable offensive skill? Maybe if you discount offensive rebounding and setting monster picks. But that's not what you get him for. You get him to be the defensive anchor and suck up defensive rebounds. His age doesn't bother me. He is still putting up. 9 PPG and 11 RPG while being a great last line of defense.
Chandler wouldn't be a bad target but a sign and trade of KO is very unlikely. I don't think Phoenix would be interested in KO. You'd have to let KO go to get Hayward and then work a Bradley for Chandler trade.
That works too. I just think Chandler would fill the Amir Johnson role but with amazing rebounding and better defense, especially down low. He isn't the defender he once was but as a former DPOY, he is still a great down low defender.
