And D'antoni had Kobe, Nash, Howard, Pau Gasol, and the Artest formerly known as Metta-World Peace. He utterly failed to develop a system that was tailored to the most stacked starting five of all time with something approaching coherence and tried to force Wes Johnson (Wes Johnson!) and Shawne Williams (Shawne Williams!) to play the starting 4 because Pau Gasol isn't a very good three point shooter. He couldn't figure out how to use a twin towers frontcourt to bully other teams into submission. He couldn't manage volatile personalities (Kobe, Dwight.) The D'antoni system is the polar opposite of what Cousins and Gay are great at.
D'antoni is a system coach who failed with numerous superstar teams and succeeded with one, in part because he had a prime Shawn Marion filling in holes on defense and defending 1-5 depending on the matchups (seriously, prime Shawn Marion > Prime Lebron on the defensive end of the floor.) The Kings have Derrick Williams who can defend multiple positions by letting them get to the rim at equal rates. D'antoni could, possibly, be good with the right team again IF an owner would trust him as coach/GM so he could go get the players his system demands. He would be a complete disaster with Cousins on the team and might make me wish for the halcyon days of Keith F. Smart.
