Illegal Substitution

[Nevadaref]

Rut, since you are an experienced football official allow me ask you a serious question that relates to this thread.

Would you have called the offside penalty against the player from Louisville on the FG attempt by Rutgers at the end of that game?

I hope that you saw the play, but if not here's the gist of it.
The player clearly crossed the line of scrimmage prior to the snap of the ball, but he didn't touch anyone, nor did he continue to rush. He stopped and actually backed up as the offense snapped the ball and took the kick, which they missed. Did he affect the play?
