Keeping in mind that I am only in D.IV, from the data I have gathered so far about my team, the Shooting Guard is the primary offensive player in almost every offense that is balanced or outside. The Point Guard is usually third behind the Small Forward. This is based on Shot Attempts recorded so far.
I think I would rather have the better defense on the point guard. They tend to get more steals in M2M and Full Court Pressure than the other outside players since they are usually the first to meet the opposing team's ball handler.
Looking at your proposals, you could probably get away with that second SG stat set, so that both guard positions are good defenders. Because, as I have seen, if the Shooting Guard is shooting a lot, you want to be able to defend that.
I would also probably not go for the 14 in Passing, but instead 15 in Handling for the SG. He is going to have the ball a lot and would probably benefit more from not being stripped and less from throwing good passes. I hope that helps.
