Harrison is obviously not 100 hundred percent. For anyone to say that Goodell hasnt changed the way he is playing is misguided. The man threatened to retire. Goodell has changed the way the WHOLE league has played. You have to learn to tackle a whole different way. Before the fines was Ryan clark getting concust as much as he is now? The concussions come from changing the way he tackles. Then new way of tackling hurts the defender and protects the offensive player. The new rules takes away a lot of Deebo's agression. When you have to worry about that flag being thrown your way it takes your mind off of the task at hand. He seems like he is playing while looking over his shoulder.
