At some point in life, everyone learns that age-old saying, "actions speak louder than words." It can be applied to many different scenarios, but the meaning of it is that what someone does holds much more weight than what they say. We can say we want to be a better person, but what are we doing to be that better person? It's what we do to achieve that end-goal, which has more value than what we say we will do.
The football field is no different. A team can say they plan to control the line of scrimmage, but until they do that, their words are meaningless.
