The line and the backfield
Can a tackle be an eligible receiver in high school?
Short answer
Not while he wears a number from 50 to 79. In high school, receivers are eligible by position and number (NFHS 7-5-6a), and there is no reporting. A 50-79 tackle may line up on the end, and the formation is legal, but he stays ineligible. The NFL’s "tackle eligible" works only because NFL linemen can report (5-3-1).

Position and number
NFHS 7-5-6a makes a player eligible only if he is in an eligible position (an end or a back) and wears an eligible number. A tackle numbered 50-79 fails the number test wherever he lines up.
Putting him on the end is still a legal formation (7-2-5 lists no end-man requirement). He is simply ineligible. See tackle over.
How the NFL is different
In the NFL a player with an ineligible number may report to the Referee as eligible (5-3-1) and then line up in an eligible position. Unreported on the end, he makes it an illegal formation (7-5-1(b), (e)). College, like high school, has no reporting: a 50-79 end is ineligible (NCAA 7-3-3-c).
If you want a big receiver
He needs an eligible number. Then he no longer counts toward the five players on the line who must wear 50-79 (7-2-5b), so someone else has to.
The Playbook Caller checks alignment at the snap only. Motion, shifts, timing, contact and penalties are not judged.
3 things coaches get wrong
- Copying the NFL "tackle eligible" into a high-school game. Without reporting, he cannot become eligible.
- Thinking the tackle on the end is an illegal formation in high school. It is legal; only a pass to him is the problem.
- Giving the big receiver an eligible number and forgetting he no longer counts toward the five 50-79 linemen.
Questions coaches ask
Can a high-school lineman report as eligible?
No. There is no reporting rule in high school. Eligibility depends on position and number at the snap.
Is it different in college?
No. A college end numbered 50-79 is ineligible (NCAA 7-3-3-c), and college has no reporting either.
Does The Playbook Caller flag the pass?
No. The app checks alignment at the snap. It shows the tackle on the end as legal under NFHS and NCAA and as a flag under NFL rules unless he reports.

Check the formations you actually run
Drag a player and The Playbook Caller re-checks the formation under your rule book. If it breaks a rule, it tells you what is wrong and shows the rule behind it.
