The pen was great to watch and I'll never understand this mindset of "not humiliating too much" your opponent. I mean wtf is wrong with football, as long as you win without breaking the rules everything should be fine.
With this kinda logic, you can criticize a lot of different things happening in football ("what did the player gain by dribbling when he could have past it "etc etc..).
They tried something original with a lot of risk of laughter on them if it didn't work. You say Suarez took a worse shot because of the angle but look at the distance (closer than the pen spot). I honestly think it's depressing to view football this way.
Football is entertainment and they found the best solution to do it while giving Suarez a hat trick. What's not to love there ?
It's not original, it was first done about 60 years ago and against Iceland no less. The reason it isn't done much is because you're setting yourself up for a worse chance unless everything goes perfectly. Like I said, he was a tiny bit closer but had to take a shot from a tighter angle.
Suarez entered the box before Messi took the penalty and so the penalty was illegal. What you do in that case is award the defending team an indirect free kick from the penalty spot. There's a reason why the ball has to move forward, why the kicker can't stop in his run-up and why he can't fake taking the penalty.
I'm not saying it's illegal and I'm not advocating that it should be. I just think given what rules are in place and how referee's can enforce them it wouldn't surprise me to see a ref make an unsporting behavior call on this kind of penalty. As a manager I'd probably be annoyed with this kind of penalty.
Suarez getting a hat trick, that's not something to love.
