It was Laquoan Treadwell and I agree with your comment.After seeing the barn break Metcalf's leg, which cost Ole Miss the game when he fumbled, and my Grandson having his leg broken in a HS game on a horse collar tackle, which was NOT called, I am in favor of any rule that prevents any type of drag down from behind which is initiated above the waist. Tackle the runner below the waist. If you can't do that, too bad. Don't break his leg pulling him down from above the waist.
