It takes 5 minutes to have a shoot out and decide a winner.
That happens in knockout games. There is a "depth" to the struggle to emerge from a round-robin group. A 0-0 tie very often holds great significance. The second half of USA v England was pretty thrilling because one goal might have meant victory: the last 10 minutes were akin to a sudden-death contest. The fact that neither team scored, despite struggling so hard to score one, has drama-inducing implications for the remaining two fixtures. You'll get your penalty shootouts in the Round of 16 and thereafter. It's the very nature of the tournament.
