The Phoenix Suns are in desperate need of a point guard (at least fans believe so, ownership and management might think otherwise).
The Philadelphia 76ers used to have a point guard who was drafted first overall, but due to some sever shooting issues, they couldn’t hang onto him while making a championship run.
The Phoenix Suns have a number of young and future assets that can be used as trade pieces (and all of which should be considered in trades to upgrade the team).
The Philadelphia 76ers wanted both future assets as well as assets that could help them right now.
