The New York Giants hold the NFL record of most playoff appearances with 31.
Neville Southall 751 appearances
who holds the record for most 3 pointers made in a playoff game and how many from the san antonio spurs
The Indianapolis Colts hold the record for the last decade, 9 appearances in the last 10 years. 2000, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009. They did not make the playoffs in 2001. If they make the playoffs in 2010, they will still have 9 appearances in the last 10 years, and will tie the record of the most consecutive playoff appearances in the NFL.
I believe John Stockton holds the record with 19 straight playoff appearences, which also happen to be on the same team, Utah Jazz.
Larry Robinson amassed 109 assists in 203 playoff appearances for the Habs. His 203 games by the way is also a Hab record for most playoff appearances by a Montreal player.
