Early in the first quarter on the Seattle Seahawks’ second drive against the Philadelphia Eagles, rookie running back C.J. Prosise broke free for a 72-yard touchdown run.

How did it happen?

The Seahawks call an inside zone running play to the left on 2nd-and-2 at the their own 28-yard line:

Immediately after the snap, Seattle’s offensive line combination blocks the two interior defensive lineman for the Eagles. Prosise reads the A-gap between the center and the right guard, seeing the linebacker penetrating through the hole.

Right guard (76) Germain Ifedi releases from his combination block to box out inside linebacker (53) Nigel Bradham while right tackle (79) Garry Gilliam finishes his block on (91) Fletcher Cox.

Prosise cuts behind Bradham wisely, while reading wide receiver (89) Doug Baldwin’s excellent block on safety (26) Jaylen Watkins who approached the box pre-snap. Free safety (23) Rodney McLeod aggressively attacks the hole between Gilliam and Baldwin and this is what opens the path for the long touchdown score. Prosise out-sprints the rest of the defense taking advantage of McLeod’s overly aggressive angle.

Sadly, Prosise exited the game early due to a shoulder injury. Hopefully he’ll make a full recovery because it’s already clear after only a few NFL games that Prosise is an exceptional talent.

The Seahawks went on to win 26-15, by the way.
