Alignment of offensive linemen
 

Are all players nominally on the line of scrimmage supposed to be evenly aligned
(helmet on an extended line through the belt of the center?)

of course, you see most offensive tackles set well behind the adjacent guard
nowadays, often in a two-point stance.)

There's no such requirement.

Mike, the rule is quoted below. Lineman may be staggered, but they must all break the plane through the snapper's waist.

FED 2-32-9 A lineman is any A player who is facing his opponent’s goal line with the line of his shoulders approximately parallel thereto and with his head or foot breaking an imaginary plane drawn parallel to the line of scrimmage through the waist of the snapper when the ball is snapped.

and nobody calls it that way! Just for the record. Waist is wear your belt is BTW!

Only speak for your area and the crews you see. Not the case here or with my crew. Usually teams are rather legal in this respect. It is rare I see that are not pretty much legal.

Peace

Once again, bigjohn thinks he knows everything about everybody, everywhere. :o

OK, lets put it this way, most crews will try to fix it before they don't call it. :p

Maybe in P & R, but I know we call it here after we try to correct it.

We tell 'em "Move up" one time. After that, flag.
