How do you know though if you’ve never been around a coach that instilled drive. I’ve only had one teacher/mentor in all of high school all of college and all of my 5 years post graduate work that include a doctorate that I felt motivated me.
I have been around plenty of coaches but that doesn't have anything to do with what we are talking about.
I agree with Colin, desire and drive is an internal thing. I agree with you, as far as, a coach can maximize those characteristics of the players, bring out the best but I guess where we disagree is you believe that a coach can instill those in a player, whereas I do not.
