Calm, cool, and collected. Unless you're a kicker or maybe a quarterback in the NFL, these three adjectives are rarely associated when describing professional football players. These three words are better used for the less physical professional sports like golf and ice-skating, were keeping one's emotions in check is more of a priority.
Professional football is a run fast, hit hard sport where physicality is at a premium and emotions can run rampant in any given moment. That's what makes this sport so intriguing and entertaining. The NFL is almost like the modern-day version of watching gladiators battle it out in hand-to-hand combat to death, only less bloody and lethal.
