I think I now understand why Jason tries to do too much too fast on the block. He doesn't recognize when the help defender comes to double him, which is why he is often blocked or gets picked and he looks oblivious. The times he does see the double, he doesn't react correctly. So, when he is looking to score, he wants to make sure he gets the shot off before any double might come, so he tries too hard and ends up with wild shots.
