One element of BBIQ is passing ability. With passing, you either have it or you don't. You either see the court and react quickly and pass the ball accurately or you don't. If you don't have that vision-reaction ability you just have to play much more conservatively so you don't make the stupid play. We have a lot of the latter kind of players. I think music is a good example, but I come to a different conclusion than you apparently. I'm a "mechanic" when it comes to playing the guitar. My nephew, on the other hand, is a prodigy. I will never come close to his stratosphere when it comes to playing. He "sees the floor" and I see "the man in front of me." (I hate him.
) Same holds for a guy with the IQ for basketball. Some guys are like Jason Thompson and it takes him nearly 4 years to know that his hands are not totally vertical (90 degrees) to the floor when he's guarding his man, more like 45 degrees. Some, on the other hand, are like Sauce and have an intuitive feel for the game.
I think Karl recognizes what can be taught and what can't be taught, and I believe that FO discussions with Karl will definitely touch on those players that are "beyond redemption" and those he believes have a future with this team. I also believe that BBIQ is going to be a major factor in their draft decision. I doubt they are going to draft someone who doesn't have the ability to deal with steep learning curve. Karl had enough of that kind of frustration last year; he doesn't want to add to it.
I'll give you this. Some players have a natural ability to understand the game. Call it what you want, instinctive, or feel for the game etc. But it does exist. It's the same as if you took a hundred people at random, and put them in a classroom with a math teacher. Some will pick it up much faster than others, and it has nothing to do with intelligence. The people that don't pick up math as quickly, might be a whiz at history. That said, regardless of your having a natural instinct or not, you can improve with hard work. But it's likely you'll never reach your perceived potential.
There's such a fine line between confidence, and real ability. If your not confident, you've already failed, but if your over confident, your a bull in a china shop. So a player walks that fine line between knowing what he can and can't do, and thinking he can do everything. By the time you've played in the league for 5 or 6 years, and your still in the league, you've probably figured it out. But when your a rookie, you feel like your in a car at the Indy 500 going 100 miles an hour, while everyone else is going 190 miles and hour. Your just trying to get around the track and not get killed doing it. When you were 15 yr's old, you were watching Lebron on TV. He was your idol. Now it's three years later, and your on the court guarding him. That's the reality of what its like to be a rookie in the NBA.
I have no idea whether McLemore will live up to his supposed potential. However, I do think he'll improve, and somewhere along the line, the team, whichever team it is, and he, will figure out what his role in the NBA is. He may never turn into that player that can carry a team when needed, but I do think he'll be a valuable player in some capacity. I do think that too many times we blame a young player for not living up to our expectations, which may not be his. Too often, a rookie is looked at as a savior, when in reality, he needs saving. That's an exaggeration of course, but I think you get my meaning.
You started with passing ability as a sign of BBIQ, or lack thereof. Which ever is the case. I agree to the extent, that some players will never be great, or maybe even good passers. But they can be taught to not be bad passers. Part of being a productive player is knowing what you can and can't do. Of course if your playing on a team where passing ability is at a premium, then maybe your not a good fit on that team.
