While it may seem unlikely, Duncan may be one of the most underrated great players of all time. Whenever his Spurs have needed him to deliver in the playoffs, he's been there. Whether it was his almost quadruple-double in the 2005 Finals or the shocking three-pointer against the Suns in 2008, he has made numerous huge plays in key situations for his team. There's a reason, after all, that he has been the constant in the Spurs' four championship runs from 1999 until today, and a huge reason why even at age 37 he's got them right back in the NBA Finals again this year.
