So what does this mean for the Cavaliers? Well, with the addition of Ariza, I think that pretty much seals the fact that the Wizards will select Bradley Beal with the 3rd pick in the draft. Ariza is a good enough player and does many of the same things that Michael Kidd-Gilchrist would do. That leaves shooting guard as the main gaping hole in the Wizards' lineup. Beal will likely be the pick and that may mean that MKG will fall to Cleveland. We shall see.
To back up my point, here's the most recent DraftExpress mock draft with adjustments made after the trade.
