I don't want to speak for Oz, he can speak for himself and do so well, I will give you my reply as my own opinion.
First off, what in the world does fake good mean, never heard such a term, strikes me a bit like saying "HOT ICE CREAM", just a term that makes no sense to me? A team is as good as it's results, no more and no less, we were as good as we finished last season, maybe we should have been better, I for sure think we should have been better, we had in my opinion really bad coaching decisions that placed the talent we had in bad positions to succeed.
What should we have done you ask, easy, the exact opposite of what we actually did do. Rather than be a half court team we should have run the the Carolina breaks, rather than play 2 centers and have 1 posted outside of the 3pt arch we should have used more of the twin tower look ala Henson and Zeller for example. Rather than yet again limit the bench we should have gone to it early season and on because those fellas on your bench need PT to improve. Maybe when guys were taking big volume shots you stop him from doing so and bench him if he does it again. Maybe you really realize the tenor of the game at the tip and not just realize the other team was more ready to play than your players were but you actually do something about that, like use your bench to send that message. How about simply not having your weakest jump shooter stand outside the 3pt arch in the deep corner and continue to let him take shots the defense wants him to take? How about in your post game PC you don't praise players as playing great when the game we just watched they clearly were not? How about not running a spread offense that requires great out side shooting while having one of the worst shooting teams in the country, how about actually spreading out the defense, at very least force them to move out of their natural positions rather than just spread your offense and allow the defense to multi battle Bacot by himself? How about actually having a PG on the floor, that would have been nice.
You ask what our rotations would look like, mine may not have been as popular but I would have first had the closest thing I had to a PG not just on the floor a lot more but I would have started him, I would have started Trimble at the point right after that awful Portland road trip, would have sat RJ and had him back up both the point and the 2, because we would be running much more, there would be no 35+ minute guys. Nance would come off the bench to back up Bacot, would have moved Leaky down to the 4 and started Nickel at the 3, Leaky would NOT, repeat NOT be a stretchy 4. Styles and McKoy would have both played much more minutes, keep in mind again that we would be more of the Roy running high pace team than the half court team we have been the last 2 seasons so you have to keep fresh legs out there, even Shaver would have got a few minutes each game.
