While winning the 1st pick is cause for celebration in, and of itself, this would be the unprecedented THIRD Time in the past ten years.
In 2003, we should all remember that Cleveland used its #1 pick to select Lebron James to elevate the franchise from obscurity. And of course, after Lebron jetted to Miami in free agency, the 2011 #1 pick was used on eventual Rookie of the Year Kyrie Irving.
