Oh I know its Morey ball, but he hired D'Antoni because he is a OG small ball coach, do you remember his Suns of early 00s? committed full time small ball run and gun 7 seconds play style, with small forward shawn Marion as only big in certain playoff series (and 6'9 Stoudamire forced to be center starter when he wants to be PF), in a time when everyone played with 2 bigs. They ran people off the floor with smaller size, speed, skill, shooting. Super entertaining.
Tell me how a coach who wants this every time he gets free reign to do his thing (suns and rockets), plays with Embiid who needs to be post player to do damage, and a Simmons that cant shoot.
What ruins D'Antoni rockets is the Westbrook trade, Morey didnt want it either, but Harden couldnt work with Paul so he forced their hand. But Westbrook is awful for a system like this, because he is a sketchy shooter, it would be 5 times worse with a non shooter as simmons for D'Antoni.
