- In the NFL, each hash mark is 70’ 9” from the closest sideline. That makes the two rows of hash marks 18’ 6” apart.
- In college, the hash marks are closer to the sidelines. The hash marks are 60 feet from the nearest sideline, making the two rows of hash marks 40 feet apart.
How does that affect the game? For one, college place-kickers (if they’re kicking from a hash mark), have a tougher angle (and kick) than a pro kicker. And when the ball is marked on a hash mark in college, the offensive team has less in-bounds territory on one side.
In the pros, the closer hash marks give a team more field to work with.
This is an often overlooked part of the conversation, Coen even said early in the year it took him time to adjust. In essence it gives the defense less ground to cover on the backside and allows them to "cheat" to the open side of the field. This takes away one of the advantages to the wide zone in making defenses react and over flow. I think we see a hybrid that Coen and staff worked and adapted throughout the season last year.
