Challenging, Exciting, Dedication, and sometimes complicated.
The game is very challenging - it takes a lot of dedication and time to play this game. As a head coach you have to experience: the NFL Draft, numerous signing processes, gameplanning, training, coaching, and performance.
The best part about the game is how it makes you respect and understand the game of football. My experience from the game showed me that I needed to give my coaches and fellow teammates more respect and dignity. Head coach gives you the point of view from the coaching side of the ball, rather than the player. Through the experience as a coach I believe you can become a better, more efficient, and dedicated football player.
Although this is just my opinoin, to really know the contents and thoughts about the game, you have to play the game yourself.
