If there are more than 7 on the line only the 2 ends can receive a forward pass beyond the line of scrimmage correct?


X          Y           LT LG C RG PG RT  TE    Z

                                 TB

only x and z are eligible correct? since they cover Y and TE
sorry I get confused about this rule

More than seven on the line doesn't necessarily only allow the ends to be eligible. The above formation dictates that but if you move off X and Z you have 8 on the line but Y and TE are eligible. There are a bunch of different combos possible to make more than the ends eligible.

More than 4 in the backfield.

I think I'm starting to get it now .. so you can have as many on the line as you want, but are only allowed up to 4 in the backfield, or off the line.  Can a guy ON the line motion parallel to the line, meaning stay ON the line while motioning? I know they can move backwards, and I know a guy in the backfield can not motion towards the line.

Negative.

Only a player in the backfield ( off the LOS ) is allow to motion.

There are basically 2 ways to draw an illegal formation call (unless you're playing by pro rules, where you can also get one based on uniform numbers, and can even be flagged before the snap):
more than 4 backs
a player who's neither a back nor a lineman nor taking advantage of the under-center QB exception

As to eligibility to receive forward passes, it's easy if you keep in mind "end" in the geometric sense rather than a designation of a player on your roster.

Ends can be in motion laterally at the snap in Canadian football.  A Texas youth league I know of also allowed it (and I mean specifically in their rules, not that their officials were snoozing on it) provided the end was moving toward the rest of the OL.

And yet, this past Sat. I saw a team in our division flagged for another: an OL with shoulders sideways to the line.

Also, if they're going by Fed rules strictly, it's fewer than 7 on the line, rather than more than 4 in the backfield.  That makes a difference in case you've accidentally got fewer than 11 players out there.  I don't know how many officials would actually flag that in kiddie ball, but there it is.
