Hey @boogielicious Personally, I agree with you about PK's.
Having said that there is some data that supports the other side of the argument.
As you probably know over the last two decades or so soccer has been the fastest growing sport in America, both in terms of kids playing it and in terms of viewership. (Some of the viewership numbers are tough to calculate due to the fact that it is often streamed rather than broadcasted, but most seem to agree that more and more folks are viewing it. Hell even my parents watch it and I can literally remember them saying "We'll never watch soccer.... blah blah blah..."
Anyway, a lot of people who are smarter than me believe those viewers have come at the expense of folks watching baseball. Baseball's viewership in the US is lower than its ever been.
So, where am I going with this?
Well, there are those that profess that one thing people like about soccer is that it's over in 90 minutes... maybe 100 minutes with some added time from the referees. Rarely any longer than that. You pretty much know that when you sit down to watch a soccer game in less than 2 hours you can get back to your life.
Baseball, on the other hand, had been up until the 1950's been about a 90 minute game. (I know, there's not clock, so it varies. But that was about the average.) Even the World Series games didn't last much longer than that. Then during the television era the game stretched to about 2-1/2 hours, which is where it was as late as the early 1990's. Now, a baseball game is about a 4 hour or more investment of time. Some of the recent World Series have stretched past the 5 hour mark.
So, although I'd prefer another way to end the games other than penalty kicks. I do appreciate the fact that soccer seems to realize that everyone is busy. We need to get back to our lives.
AND ... I do think it is one of the reasons soccer has in a lot of ways over-taken baseball in terms of fandom and participation. It's a choice between watching an event which might take 90 minutes and an event which might take 5 hours.
So, I don't like ending the game with PK's.... But I kinda like em too.
