I don't think O'Antoni is a bad coach, just not a great one. I like the improvements we've made and our core of players, but I think his basketball philosophy hurts more than it helps.
IMO, the SSOL offense serves as entertainment for the fans. This is not all bad since it puts people in the seats BUT its very one-sided and is only successful when the majority of shots are being made. Another reason I dislike the system is because it doesn't maximize players key strengths.
Example #1 - When O'antoni got here, he immediately started having Chandler shoot 3s as if that was his strength. Instead of keeping him out on the 3 pt line he should have been involved in motion schemes where he could drive to the basket more. I will note that Chandler has turned into a nice all around player.
Example #2 - Bill Walker came into the league with lots of talent (check his videos) and was a projected lottery pick before the injury. Now it's a shame how O'Antoni has forced BW into nothing more than a Steve Kerr or Eddie House type player. BW is not easy to guard since he can knock down the 3 with good accuracy plus take it to the basket strong. Too bad coach doesn't know how to maximize his talents.
Example #3 - Mozgov and AR bring size to the table which is something we are sorely lacking yet they can't crack the rotation. Anything that disrupts his speedball is not an option for him. When AR first got here coach said he was valuable because on most nights he could guard anywhere from 1 to 5. What happened? Why dismiss what he could bring defensively just because he doesn't quite fit your precious offense?
