Again, can you specify what problems you're alluding to? I'm trying to take all the heat I can but you don't specify what the problems are so I can adress them. I don't think it looks very good when you are criticizing me but not answer me directly.Well, when it comes to that sentence I highlighted, I could read it a hundred times and still not know what the heck he's talking about. As for the other stuff, yes, there are problems with what he said. I'm all for somebody giving it a try to help other players and being a little humble about their lack of knowledge. But if you're going to act like an expert, then you'd better be able to take the heat.
The problem with your solution is that while it does 'fix' the problem of arm position, it doesn't address the cause of the mechanical flaw.
The elegant solution is to just change where the feet are and get down naturally from there.
With that stance there's not a lot of other ways the player will put both his head and hand on the shot line, you can try it yourself. We have three anchor points and we would like to build a tripod, this player has all anchors on the same line. You can bump him on the hip to get him to feel how unbalanced he is, then probably he will put his left foot more to the left while keeping the right foot somewhere close to the shot line. Then he can rotate his ribcage to the right and get his whole arm rotated counter clockwise to make the arm hang straight down.
If you tell him that he should be able to take a small bump from both sides (and give him one when he stands like this) he will probably sort out that stance pretty fast.
