After a full season of games and play-offs, the two contenders--Los Angeles Galaxy and Real Salt Lake--battled to a 1-1 tie in regulation. They were still tied after another 30 minutes of extra time. So, rather than continue playing SOCCER until a winner emerged, the entire season came down to a round of penalty kicks.
It would be like deciding the World Series with a home-run derby; the NBA championship with a 3-pt contest; or the Superbowl with a series of ever longer alternating field goal kicks.
Penalty kicks are not soccer. They don't even require all that much skill. Some people think it's a "dramatic" way to finish games (Real Salt Lake made the championship game by winning it's division in yet another PK finish), but if that's so, why not just create a game based around shooting PK's?
The problem, of course, is that modern soccer has evolved into a defensive struggle in which teams seldom dare to take chances in order to score. A ridiculous number of games end in 0-0 and 1-1 ties, and the concept of "sudden death" overtime has never caught on.
Because the game is difficult to resolve within the game format, modern soccer has devolved into PK contests that demean the sport.
MLS should ban the PK as a means of deciding games that require a decision. Such games should be decided on the field, in a sudden death format, with no limit on the time to be played until the game is finished. Those games will have dramatic finishes, you can be sure.
