"I'm not you, Dad"
Now if Coach Mena were to say "Marco, today I want you to run with Darius. Stick like a fly to glue. No matter what, don't let Darius get away" Marco would shake his head and say "OK, coach". Then he would do what coach asked.
This is not a Dad feeling sorry for himself. This is a guy who admires that Father/Son coaching thing and is quite happy to admit finally that it's not in the cards for Marco and I. Today it's official "I am not your coach".
It's a good life...
