Of course but refs are human and make mistakes. Say 1 in every 10 or so penalty decisions is a howler. So if as a team you create 20 more chances to get a pen than another team then you'd on balance get another 2 pens. You'll also statistically get more going the other way too where the ref doesn't award them and that's a howler too. So probably evens out over a season.
I’m fine with pens being given, as long as they are pens. I hate the idea of ‘creating chances’ to get a pen, you’re creating chances to score a goal? The idea that you’re going to keep diving and eventually one of them will stick winds me up, that’s where we’re at.
