I actually agree with both of you. In the early seventies we put a great deal of time into special teams, 2 minute drills, wet ball practice (when dry and 90 degrees), holding onto the ball and recovering fumbles. BUT practice started at 2:30 finished at six on Monday, 7:00 on Tuesday, 5:30 on Wednesday and Thursday pregame film only. You can’t do what we did with the shorter practices and the multiple formations and more complicated defenses of today.
