My only real issue with soccer is extra time. From my limited understanding of it, it seems pretty arbitrary, no? And are both teams notified in advance as to if there is going to be extra time? Because i can see a team being frustrated with it if they have a lead or something.
But naw, i don't care for football mainly because it's just barely better than baseball as far as entertainment goes. Love me some b-ball, though.
It's pretty much like this:
* The biggest decider for amount of extra time is how many substitutions there have been. The rule of thumb is each one adds 30 seconds (they may or may not take this long). So six allowed subs * 30 = 3 minutes added. Which coindidentally is by far the most common extra time in the second half. In the first half, there usually aren't any subs, so it's usually 1 minute if there was an injury or something, or even more common no extra time at all.
* Only blatant forms of intentional delaying from the team which benefits from it (leading, or needing draw to advance or something) will cause time to get added to the extra time clock.
* It's very uncommon for second half extra time to be anything other than 3-5 minutes.
* The players are notified at the 90 minute mark if there is any extra time, and how much.
Example: first half, nothing happens, no goals, no injuries. No added time
Second half: all six substitutions, three goals, no injuries. Probably four minutes added.
It probably seems stupid from an outside perspective but I think it works fine.
