I imagine you've done some coaching so you know that people learn almost nothing when they're uncomfortable and generally confused. You need to get them in their compfort zone and then extend the boundaries of that.
I'm not an athlete, so I haven't done athletic coaching, but teaching is similar, and I've done plenty of that. Yes, you have to work with the student from where he is.
Those situations are easy to read and he knows what to do - and he's fairly successful.
Right. He can be successful when the task is conceptually easy and within his limited skill set.
I would have one of the assistant coaches assigned to giving Len those specific things. Decide ahead of time who Len is going to defend in the next game then the assistant and he go over recent video of that player and work out what Len should do.
I think that this could be an effective way of developing him. My point is that most of the players he'll be competing against have gone through this stage many years ago.
If we see Len raoming or standing around looking lost this year like he did last year, its primarily bad coaching.
I wouldn't go that far. How a game develops is not within any coach's control, and certainly not to the degree necessary to keep Len's inexperience from being exposed. If Len gets to be a factor and other teams realize that he is easily taken out of his comfort zone, then that's exactly what they'll do.
Len reminds me of Tsakalidis. I remember one game against the Jazz that came down to the final possession, with Utah having the ball. The Suns' coaching staff (whoever they were then) correctly predicted that Karl Malone would get the ball at the elbow. They set Tsakalidis up to smother Malone when that happened. He did it, Malone was caught by surprise, he couldn't get a shot up, and the Suns won. It was an effective play, but it did not mean that Tsakalidis was a good defender in general.
I'm sure that Len could come to our school gym and dominate. His body is large and functional and he does have some basketball skill. But the gap between him and a real NBA player is cavernous.
