Look. I agree with a lot of what this guy says. Confusion when getting set (that's a major pet peeve of mine. If you have limited practice time and you don't know from week to week who will be available, stop overcomplicating things), certain elements of technique, playing to soft, etc. are also legit. But when it comes to a particular defensive set it's easy to use hindsight to criticize. Defense is sometimes a gamble. Sometimes you win. Sometimes you lose. I still want to know where this guy got all this knowledge, I can't find a reference to that anywhere. Are we listening to amateur night or does he have some background to back this up.
