Tight End Covered/Uncovered

[The Roamin' Umpire]

NFL rules are from www.nfl.com/fans/rules/

Formation - NFHS:
The offense must have a minimum of seven men on the line of scrimmage. Anyone not on the line must clearly be a back (i.e. not breaking the plane of the nearest lineman's waist), except for a QB under center.
Formation - NFL:
Same, except that players not on the line must be one yard behind the line of scrimmage.
Eligibility - NFHS:
All backs are eligible, and linemen on either end of the line are eligible, but only if wearing a number 1-49 or 80-99.
Eligibility - NFL:
Backs are eligible, except for a QB under center. Ends are eligible unless a center, guard, or tackle. (I read this as meaning the snapper, and the two guys to either side of him.)
