2013 NLL season

The 2013 National Lacrosse League season, the 27th in the history of the NLL, began on January 5, 2013 and ended with the Championship game on May 11, 2013. The Rochester Knighthawks overcame a mediocre 8-8 season to get hot in the playoffs for the second straight year, defeating the Philadelphia Wings, Minnesota Swarm, and Washington Stealth to win their second straight Championship. The Knighthawks became the first team to repeat as NLL Champions since the 2002-2003 Toronto Rock.

2013 featured a very close regular season, as the top and bottom teams were only separated by 4 games (the 10-6 Toronto Rock vs. 6-10 Buffalo Bandits). The final playoff spot was up for grabs right up until the final weekend of the season. In the end, the Bandits were the lone team out of the playoffs, missed the post-season for the first time since 2002.

Playoffs
•Final played at Langley Events Centre due to arena conflict in Washington.

NOTE: In 2013, the NLL added a crossover rule to the playoff format:

"Eight teams shall earn playoff berths. There is also a crossover allowed which will allow the 5th place team in the West Division to take the place of the 4th place team in the East Division if the 5th place team has a better record. Each division champion faces the fourth place finisher from their division (or the crossover team should that team qualify for the playoffs). The second place finisher in each division faces the third place finisher from their division in the Division Semifinals. Each game is hosted by the higher-seeded team."

With a record of 7-9, the Minnesota Swarm was the 5th place West Division team. With a record of 6-10, the Buffalo Bandits were the 4th place East Division team. Since Minnesota had a better record than Buffalo, the crossover rule went into effect with Minnesota replacing Buffalo and playing as the 4th place team in the East Division playoffs.
