Football needs extra time, and it needs penalties.
But what if we switched up the methods of getting there?
Imagine, after 90 minutes, 11 players walked back out on the field of a tied game ready to play another 30 minutes. Then, every five minutes, one player from each team must leave the pitch. At 95 minutes, it's 10 vs. 10. After the first 15 minutes, only eight players are going back out there.
Now, it's more complicated than losing someone every five minutes. Once the 30 minutes are up, only five players will remain. And guess who has to take the penalties?
Those five players.
More importantly, though, if the kicks go longer than five, they must go to the players that were taken off in overtime. Rather than just any players, though, they must send out the kickers in order of their departure. For example, the first player off is the sixth kicker; the second is the seventh and so on.
With this rule in effect, a coach must look further than his five best penalty takers. He must take into account the position, fitness and nerves. Moreover, it would allow coaches to keep their goalkeepers on the pitch until the end, making them the last players off and the last kick takers.
By implementing this rule, extra time becomes much more of a mind game. It wouldn't be a dull half hour with an inevitable penalty-kick ending. Instead, it would be a nerve-filled mind game that would test coaches, players and their relationships, while becoming a much better product for the fans.
