I wouldn't get ahead of yourself dude. You have about 22% - 23% chance of the first overall pick, and it'd be much less likely that you also get the 3rd pick. And even if you do get the 3rd pick (which I highly doubt) I don't think you'd get Irving too because the 2nd team can always trade the pick, or pick up Irving and trade someone else, or simply just draft Irving because he's the best player available.
In addition, even if the Cavs get Irving and Williams, that still won't make them a top team for a while, if at all. So you're getting like 5 steps ahead of yourself dude. You should wait until tonight before you keep dreaming.
