There was a thread on RealGM a Wizards fan made earlier in the season about how poor John's handle is for a PG.
I wholeheartedly agree with him too. But like he said, it's up to the management and FO to make him work on his flaws and reach his full potential.
There are some things that I don't agree with the op on. He acts like Wall is Superman and should be able to learn everything on the fly. And we all knew he was a raw prospect out of college and that he had some flaws (including his handles). Him being that raw and rough around the edges, and still being the 2nd-best college basketball show just how great he can become. He has all the tools.
