Streaks In American Sports
Now that the NFL regular season is over, I have gone and updated my list of consecutive playoff appearances in American Sports (MLB, MLS, NBA, NHL, NFL, and WNBA). None of the changes affect the Galaxy's position as the fifth longest, because the NFL is full of parity.
I've also made a list of the most consecutive winning seasons (over .500 win pct) in American sports as well. That list has lower numbers that the first, because it's easy to make the playoffs without having a winning record, except in baseball and football. The Wizards currently have three winning seasons in a row, tops in MLS.
For the entire lists, see this Bigsoccer thread.
