I am assuming you are responding to the troll I have blocked, so I apologize if I am missing some context to your post.
This is the same discussion/ argument we had over who was going to get waived- Canaan or Harrison. Canaan is an actual NBA player. Perhaps not a very good one, but he is an NBA player. It's the process of elimination. Harrison was not an NBA player, so he is gone. Okobo and Melton are not NBA players, at least not yet. They are rookies. Canaan is an actual NBA player, and he is the best we've got at PG right now. He is a competent shooter, ball-handler, defender, and a passer. He is not great at any of those things, but he is competent (to good) in all of them. Unless you want Booker at PG, there is no other choice when it comes to the starting point guard until Crawford is ready to go, and even then it's questionable.
Again, I *THINK* you are responding to that PG Troll that I have blocked, so please accept my apology in advance if I am missing some context.
