As a High School Offensive Coordinator myself, I feel that there is a lot of unfair criticism coming at McCarthy and this offense. ( I know that HS and the Pro Game are two Totally different levels - However Coaching Philosophy and techniques often Parallel ) And there is a huge factor on why McCarthy scripts his first 17 plays, but we'll get to that later.
As posted above, Scripting your first 10, 12, 15, or 17 plays often has many disadvantages and advantages. I read through some of the posts and most of you hit on some of these advantages, but I wanted to share my take on it. Mainly it avoids mental errors from your players, because usually those scripted plays are plays that your players preform the best on, they might be the best plays in your playbook or the worst. (i.e. they are more comfortable with that play for whatever reason)
Also, it keeps the defense totally off balance because since the play is scripted, it might be 3rd and 7, a clear passing situation, and the play on the script could be either a designed run, a screen, draw, or pass. Or it could be 1st and 5 and at that point in your script you have a 4 All Go (4 Verticals) called. It all depends on how you design your script through your week of practice and film breakdown.
Most of the time I script my first 10 based on two factors -
What plays are our players most comfortable with?
Which plays are designed to take advantage of the schemes the opposing defense tends to lean towards (what fronts do they like to run, how aggressive are they in their blitzing, which coverages do they use the most)
Once again I know the level I coach on and the level McCarthy is on are on two totally different levels, I am sure he uses somewhat of the same way of thinking while scripting. Some coaches will script others tend to disagree with it, it all comes back to how they were brought up as coaches and their overall personality type.
The biggest reason that the Packers need to script their first 17 is because of our inability to run the ball. I have read many things on our lack of being able to run the football. Which is a fair criticism, however the blame is now being put on McCarthy. What I mean by this is, is that when most people say "run the football" they mean power offense like you see the Steelers, Ravens, and Chiefs run it (There are more teams that do this well I just cant pull any off the top of my head right now). In past years we have been able to do this with some effectiveness. However with the loss of Grant we will never achieve this until our depth at the Running back position is addressed. Brandon Jackson, James Starks are not every down backs, at least from what I have seen from them.
I have heard people say "well its the coaches job to get his players ready and execute the play." This is true, but when you do not have the personnel to effectively do that, why would you call that play in a game? I know for a fact that if the coach isn't confident about it during practice, no matter what he says on NFL network or his Pressers, during the game hes not going to come out in a double tight I formation and try to pound it out.
- yes we have done this in the past couple games, especially the lions, but rarely did we see 'power' offense, a lot of draws, screens, play action passes and stretch plays were called.
This reason, our inability to run the ball effectively, goes back to scripting your first 17 plays. Why? Because when your offense is knowingly unable to run the ball at will, you have to use every tool available for you to get an advantage on the opposing defense. While they are some draw backs to scripting, the advantages outweigh the losses in my eyes.
