It depends on whether your goal is to win championships or to sell jerseys and fill stands...
The messiah is the modern day Iverson. A more talented, dynamic, and better marketed version...But the same result. It's a safe bet that he'll always have a substantial following regardless of how his team does. It's also a safe bet that like Iverson, he'll always fall short.
Durant, Kobe, Rondo, Williams, and Howard are among several on my list that I'd take over the messiah if my goal was to win a championship.
