Honestly, that's 7 points off the board if you sneak it. I still contend that Forte got a TD on the 2nd down run before he fumbled it. It looked like it from behind, but the goal line camera made it clear that he never crossed it
It was physically impossible for knox to avoid that tackle (short of stealing superman's legs) it's even tougher to avoid a tackle when you stand still If he had kept going he would have been hit harder. It was impossible for him to change direction (he tried to almost as hard as he could)
