Hash marks

Both sidesAlignmentQBWRSCB

What it is

The two rows of short lines that the ball is placed on, which split the field into a wide side and a short side.

Why it matters

Hash placement is the reason field and boundary are different jobs. High-school hashes are far wider apart than professional ones, so a high-school offense on the hash has a genuinely enormous field side and a genuinely cramped boundary — and every coverage rule that mentions field or boundary exists because of that asymmetry. It is also why the same play call is a different play from the left hash than from the right.

Also called

Programs call this hash, on the hash, field side, boundary side or wide side. The Coach answers to any of them.
