Every guard in America at every level works on their "point guard skills" i.e. dribbling, passing and decision making. That doesn't mean they're specifically training to become a point guard. They're working on their guard skills.
You've also said in the past point guard is the easiest to learn and now you say the opposite. I guess you'll give me some crazy distinction between learning the skills and learning to BE a point guard, which is actually everyone's point that opposes you. You can learn to be better at skills on the court but that doesn't necessarily make you a point guard, even if you work on those weaknesses for years.
Solo and Hawk can work on their point guard skills, and they should, until they're blue in the face. It probably will not ever result in them being a point guard, but rather a better 2 guard.
