As long as they kick it, they are good. If they run a fake then the problemo's start.
In a scrimmage kick formation on 1st-3rd downs, you need at least 4 players wearing 50-79 on the line of scrimmage -- only the snapper (between the ends) may be another number.
If not in a scrimmage kick formation, you need at least 5 players on the line numbered 50-79.
On fourth down or a kick try down, you can do whatever you want.
What you do after the ball is snapped is irrelevant.
