TD or Penalty? Analyzing the Controversial End to Notre Dame vs. FSU

This weekend’s prime time college football game featured #5 Notre Dame visiting #2 Florida State. With seconds to play, Notre Dame appeared to score the game winning TD on 4th and Goal, only to be called back for Offensive Pass Interference. But what made it Offensive Pass Interference?

The play is a common goal line pass play for many college and NFL coaches: a Slant route and a Shoot or Flat route with the hopes of a natural “pick” to make it difficult to cover in Man to Man coverage. Notre Dame ran the play from a “Bunch” formation, which is 3 Wide Receivers aligned in a triangle close together. The Apex, point man, (Middle WR) runs to the goal line and attempts to make himself a big target and box out any defender. The outside Wide Receiver runs a Slant route, and the inside most Receiver runs a Flat route. Florida State matches this with straight Cover 0: FSU is in all Man to Man with no Safety help anywhere, with everybody else blitzing. Notice the backside Tight End and Running Back do not go out for pass patterns, and the pre-snap assignments are shown below:

Dakota formation: How Julius Thomas makes it look “So Easy” vs. NYJ

Week 6’s Jets vs. Broncos match-up featured another two Julius Thomas Touchdowns, his 8th and 9th of the season. The second TD came from a formation and play the Broncos have fallen in love with in the Red Zone, a simple backside slant from the “Dakota” formation (also known as X-Iso). The Broncos have clearly revealed a tendency from this formation; the question is whether anybody can stop it. The Dakota formation features 3 Wide Receivers split wide to one side, with a Tight End split out alone as the backside Receiver. Given the Broncos personnel, the defenses must make tough decisions. Multiple defenses have decided to cover backside Tight End Julius Thomas with a Safety with no other defensive back to the lone Receiver side. The Broncos have repeatedly attacked this defense with a basic slant route. Here is a freeze frame of last year’s Chiefs v. Broncos game using a Dakota formation:
