Magic had Kareem and Worty.
Bird had Mchale and Parish
And Jordan had Pippen...
Each of these players needed some sort of help to win a championship, So I don't think our current big 3 can be knocked for this for this reason and the fact that Paul Pierce and Ray Allen were not considered First team NBA players back then, and still are not. Lebron and Wade are 2 of the top 4 players in the NBA, and they made the decision to join forces. Its definately not the same.
