Post-NBA Draft, Dwyane Wade and Chris Bosh opt-out

I'll go over everything about the 2014 NBA Draft. What I thought happened at the top of the draft, were there any major reaches? Who fell too far? Which teams had the best draft and which didn't make out too hot? Also, Dwyane Wade and Chris Bosh opted out of their deals with Miami for the 2014-15 season. What does this mean? Will they come back with LeBron? Will one or two stay? If they all come back, what do they have to do to be able to compete with the San Antonio Spurs?
