6. Tim Duncan
Don’t let his demeanor fool you, Tim Duncan is one of the greatest closers in NBA history. The unassuming superstar led his San Antonio Spurs to four NBA championships between 1999 and 2007. He captured NBA Finals MVP honors three times in 1999, 2003, and 2005. During his finals career, Duncan averaged 22.7 points per game while adding 14.4 rebounds and 3 blocks. The Spurs eliminated the Nets in game six of the 2003 Finals behind a near quadruple-double from Duncan in which he scored 21 points, grabbed 20 rebounds, dished 10 assists, and blocked eight shots. In that same series, Duncan set the record for most blocks per game in a finals series with more than five.
