The team with the most points wins. This remains the most important truth in the NFL. Now the matter of how this phenomenon ultimately happens is a part of the strategy that goes into the game that we all love. NFL teams devote all of their energy towards maximizing their odds of scoring, winning, you get the picture.
Obviously the quickest way to the endzone is the most-preferred path (generally speaking) which means you have to, well, be pretty quick. Quickness in the NFL is essentially defined as explosiveness and a big reason why the Dallas Cowboys did not get as far as we all would have liked last season is because they lacked explosive playmakers on offense.
