Happy Thanksgiving, ND Insider Premium subscribers.

In this space, I normally have a written analysis of Notre Dame’s offense from the previous game following my weekly charting and film review.

However, with the condensed week for the holiday, I’ve run out of time to complete my typical writeup. Instead of making you wait until Friday for a breakdown written on an airplane, I’m sharing with you now the numbers I chart every week. It’s the same information I provide following every game without me waxing poetic about them.

Consider it a side dish for your Thanksgiving meal rather than a full entree. I’ll be back next week with a full analysis of Notre Dame’s offense following the Stanford game.

All the numbers below are limited to the starting offense with quarterback Ian Book in Notre Dame’s 40-7 win over Boston College last Saturday.
