You are mistaken. I didnt say he pulled himself, i said he got benched. Then after the fact he decided to let them take him out for concussion because its better for him this way. Again dont be Naive. Tyrod is tough as nails and if he was winning there is zero chance he lets them take him out and put mayfield in after that weak sack.
Players get asked questions in the tent and based on their answers they go back out or not. Its up to him in that moment, given that he knew he was getting benched it only makes sense for him to answer poorly.
