Continuing the analogy, Michael Jordan doesn't get to display his full Jordan-ness on the court unless he's got a teammate like Pippen who creates opportunities and solves problems that will be huge energy drains on Jordan if only Jordan is there to solve them. (Guarding opponents; salvaging something out of busted plays, etc.)

Finding stars and paying them a lot is pretty easy. It also isn't necessarily the path to great success, especially if you can't build a coherent rest of the team. Just ask Allen Iverson.
