how many? 5? Do you watch the whole practice or just the end with the media?
Do you go to team and position meetings and watch film with the players? Do you get to see the results of the player testing that is done to ensure the players know what they are supposed to do in each meeting? What else do you do and know?
As for me I will trust the people (coaches) that are in EVERY meeting, watch taped practices over and over, and are paid to win over some guy that gets into a few practices and sees 5% of the picture.
