You should consider reading the enforcement penalty for your rule 3-7-5. It is not a 15 yd penalty. It is a 5 yd, live ball illegal substitution penalty. To achieve the 15 yd status, the covering official would have to determine the practice was deceptive (see 9-6-4d) which simply is not going to happen if the defense covers the player.
Why no answer regarding the request for explanation on how it is deceptive if the defense covers him?

editted to add : I too am bored at work, so no feeling like the Lone Ranger there, Welpe. BTW, sick of Texas yet?
