Unfair Tactic (or not?)

[jwild1665]

How about a slightly different factual scenario, where there is no substitute or replaced player used. Team A runs one play and after the play they are loosely grouped near the ball. The R blows the ready for play and A1 leaves toward the sideline while the rest of Team A huddles. They break the huddle, meanwhile A1 has stopped at the sideline. A1 goes downfield at the snap, unobserved by Team B, and catches a touchdown pass.
