Huge, huge mistake branding our league with European traditions. The league started as a unique American sport. Although not taken seriously by FIFA, it was very popular among Americans. A major complaint of the sport is that so many games end with no winner. In the early days of the league, games ending in a tie would resort to a hockey style, 1 v 1 shoutout which was extremely exciting and something totally unique to the MLS. Also, games were exactly 90 minutes and time was known by all by the use of a clock keeping official time counting down from 45 each half.
I have to disagree. The overwhelming majority of MLS fans are European and South American football fans, who were quickly alienated by the different rules from the football they were used to watching (one of numerous factors attributed to the huge decline in MLS attendance from season 1 to season 2). The rules were changed after 1998 to match those of the rest of the world. At that time, average attendance at MLS was about 14,000 fans per game. Over the past 15 seasons attendance has increased slowly to an average now over 19,000 per game.
If you prefer games to not end in a tie, have a precise clock, and (not sure if you would prefer this or not) have increased scoring, I encourage you to check out the MASL, Major Arena Soccer League. Playoffs just started for that league (which plays in hockey arenas on artificial turf) last week and while their attendance is a little sad (a couple thousand per game, max) and they have no TV deal, all the games are available to watch online.
Go Aberdeen, Newcastle, DC United, and Baltimore Blast (and Jeff Gordon)!
