I am not even sure if you are talking to me or to Joshua, but I am taking the time to calmly respond to you.
Apparently the wording "bad instincts" threw you off for some reason, so let me define what I mean by that first and provide some evidence for what I mean. Feel free to disagree or "school me" if you want to, after all discussion is always valuable.
With "bad instincts" I mean that Bamba is slow to react to what is happening on the court, especially defensively. To me, he seems to need a split second longer than he should to process what is happening. He does not anticipate quickly enough what the opposition is going to do. This manifests itself in really bad pick and roll defense. Apparently he is in the 32nd percentile in pick and roll defense. That is really bad for someone that is supposed to be a future DPOY.
For some evidence for what I mean you can watch here from 7:07 to the end:
Further, I am citing commonly acknowledged scouting sites to underline my argument:
From Draftexpress in 2015:
-While the physical tools and potential skill set are tremendous, Bamba is still extremely raw on both ends of the floor. He doesn't have great fundamentals defensively and often leaves much to be desired in the reaction time/twitch and motor department.
-Feel for the game is a work in progress. Lacks significant strength and experience. Has a long ways to go still
-Stands and watches on the defensive glass. Doesn't want to find a body. Relies on tools more than fundamentals.
2017:
-Needs to play with more toughness to maximize his defensive potential. Gets posted up without much resistance. Defensive fundamentals have room to improve. Bites on fakes. Doesn't take great angles on the perimeter.
-Over-thinks the game at times. Can play a more reactionary game

The stepien also notes the same problems:

They even have a whole article breaking down his defense (though I think this article focuses too much on athl than instincts/reaction time):

And yes, I am aware that I am off consensus with Bamba at #11 but since when did we have to agree on everything? Thats called group think.
(And its not like I have him in the second round either, just that I rank other prospects higher.)
Oh and the whole "I watch for games than you, thus my observations are more valid". Sure, someone might watch more games than anyone else. But watching the games is the easy part. The hard part is to evaluate which traits and skills translate. If you look for the right things, you can take away more from 2-3 games than if you don't and watch all games. Not saying that you specifically don't know how to (I actually agree with your analysis a lot - just not here) - just saying that these types of arguments lead us nowhere.
