Yes, there are players who make reckless challenges even when on a yellow. Those players get sent off... And the number of those players, the number of booked players getting their 2nd yellow in a game, is what... 5%? 10%?
So, again, using statistics, and common sense, it's reasonable to assume a player on a yellow card changes his game and lets up.
(yes, give us another "no s**t, Sherlock" comment - because you're the one that doesn't seem to take it into account)
I think it's pretty funny you're using Trump as an example of something when you seem to lack the basics of what makes an argument based in logic.
You cannot, by default, make an argument that "Camacho's match performance looked like a glaring example" because he never got booked.
For your argument to make any sense at all, Camacho would've had to have been booked - and THEN continued to make borderline challenges.
Your example, in fact, is the precisely the point
I'm trying to make.
Your example, in its core, cannot be used as an argument for the point you're trying to make -
because he never got booked.
How can you not see that?
