You can never evaluate everything and there is no need to.

Weekly the game planning changes as the opponent changes.

You prep for and execute the basics in preseason and then plan for the opponent specific items furring the week before the game.

Even personnel, there is just enough time to run the gamut of x,y,z and grade accordingly in the preseason because cuts are coming up and you want to make sure you keep the most value... That is also why it is still somewhat basic before we are down to 53.... Don't want someone you cut showing up in Atlanta knowing your advanced plays before the season even starts.
