I mean, they were poor quality matches. In the end, high drama, but poor quality regardless.
Most forget there are more games in this tournament though. What I mean is, for the boring matches we had because of the 16 go through out of 24, we also get 8 more games that are all in, instead of having the playoff start at the quarter finals.
Yes, some games might be more boring, but it's starting to pay off, and the fact we now have 15 games instead of 7 left until the end of the tournament, means this Euro can easily provide as many interesting games as 16-team Euros.
