Agreed, tackling has lost some of its true meaning. Too many players are trying to ram the runner rather than making a sure tackle. We were taught to keep your eyes on a runners torso, and you would not be fooled by sidesteps and other fake movements, then make a burst of agressive speed into the back, thus making him have to escape rather than giving him any advantage of the sidestep. I see way to many tacklers standing their ground rather than attacking the runner. Generally, the defensive player is sidestepped and the runner goes past him. At least, if the defensive player advances quickly toward the runner, it makes the offensive back have to divert his route giving other defensive players a chance to get to him. All of this has to be taught. When I see players not advancing toward the runner agressively and aiming toward his torso, I immediately think the defensive coaches are not doing their job.
