The way in which you've described the situation leaves some open questions. I'll make an assumption.
Some offensive coordinators like to number the outside 'hole' twice.
In your case, that would make the 7 hole the general area next to the end, and the 9 hole becomes the area well to the outside. Most youth offenses do not do that, so the 7 hole describes a sweep, run outside the ends. Assuming the latter, it sounds to me like the offense is not sound and the blocking scheme for that play is not fully thought out. In most youth defensive systems, the job of the end is to penetrate and contain, driving the play inside. If you really want to sweep against such an end, someone must keep him from crossing the line of scrimmage and block him to the inside.
