Agreed, Lebron as good as he is can affect the game in the best ways. But Dwayne wade is the best playmaker(different from getting assists) on that team in that he can make things happen in any moment much better than lebron. I am not a fan of either, but Dwade gets overlooked as the head of that team and it showed more than anything on the big stage.
for future probably, but if to pick a player for the playoffs, or final series, lebron wouldn't get it done
