OK. I am going to weigh in with the understanding that everything we are saying are our opinions.
I do think the offense would work in the NFL with the right talent to run it, but with that said, I do agree that if there were no concerns and drawbacks, an NFL team would already run the offense. The NFL is a business, and every team wants to be Super Bowl Champs. There is NO recruiting. The reason teams in the SEC do not run this offense is because they all think they can recruit better without it. I believe the reason NFL teams do not run it is because, as upstate tried to say over and over, the defensive speed/size/hitting ability would mean that a QB might last 4-5 games if lucky. You would have to have 3-4 at least with both running skills and passing skills that could take huge hits without concussions or other damage. As you guys have seen, it does take running AND passing to make this O work consistently. Also, all of the rules in the NFL have been changed over the years to make passing much easier, as the O has the decided advantage when passing the ball. Just my 2 cents.
