You can’t break the huddle and make it work, so it usually comes from a timeout, or the field goal unit just goes no huddle. I personally don’t have a problem with the play. But if it was illegal at the time, the refs screwed up, not once, but twice. The Cal Bears used the same play and the receiver was overthrown.

the PacX refs said that ND should have been charged with deceptive use of substitution. from the replay, you can see how the ND receiver hid with a pack of two players slowly walking off the field in a substitution. that is a deceptive use of substitution. as Frak said, there are instances where the play can be run legally.
