Which of the following 20 #1 overall picks are good choices, which are bad choices?

for the respective teams that drafted these players, the spurs made the best choice hes got them four rings, shaq got all his for other teams. yao was an excellent choice (no rings but brings mountainloads of cash to the rockets every year), lebron also a great choice, id even say iverson (no rings but made the sixers alot of money over his decade there).
