By that logic, every team that wins championships also needs at least two superstars. The Heat had two, the Celtics had 3.

While I love Posey (Celtics fan here), it takes a foundation of superstar talent first to even have a chance.

Many people take for granted the 20-30 points, that the team scoring leader puts up every night, and start to look elsewhere for that magic winning element. Without the consistent play of the scorer (and the attention that draws from defense) guys like Posey would be exploited by a good team.
