Only if we are rewriting the rules of football.
Which has always been - you plant your feet on the 10. If it goes behind you, you leave it.
Im assuming the coaching staff yelled at him for not letting it go, because in games after that he didn’t do that again.
Not a chance imo. When he makes the decision to leave the endzone, no blocking was set up yet. And there were not 1, but TWO defenders waiting for him at the 20. He would have had to make 2 seperate guys miss.
