Throughout my career, I have worked with many specialists who have been kicking, punting or snapping for years without any formal training. Some of these specialists have even made it into the NFL or other professional teams; and they have achieved their success on sheer determination alone. I am always amazed and impressed by that.
But as someone who has been a kicking coach for over 30 years, I can say with certainty that no matter how far a specialist gets on sheer will, determination and talent, they will always be leaving something behind if they don’t receive proper coaching or instruction to help them refine their skills and technique.
