as everyone already said back to back Finals appearences for Duncan at age 38 as one of the main pieces only adds to his legacy. Their is no doubt he is the greatest PF to ever play the game. Losing to a superior Heat team would not hurt him one bit. As far as Lebron they were expected to be here, they have 0 competition in the east. Realistically this is the 1st series where they will be tested. So definitely more on the line for Lebron.
