When Did This Rule Go Into Effect

Ooooo, good one! If you'll allow me to improve it from a coach's perspective, there are plays where a wide receiver starts on a shallow cross route, sometimes continuing as a receiver and other times cracking back on a linebacker for a sweep to the side the receiver came from. The cornerback on that side has coverage responsibility for the next receiver who comes out that side, but also responsibility against the running play. What if the CB blocks the WR in front of him as described by parepat above? At the moment of contact, because the WR is facing sideways to the CB, the WR is no longer a threat to block the CB, but is a threat to block the LB. Is the WR supposed to get free passage across, on the possibility it'll be a pass play, and so an unmolested shot at the LB if it's a run? Or is the CB supposed to be allowed to knock him off that blocking track, and thereby be allowed to mess up the pass route as well?

If it's legal, it does look like a smart play by the CB. He doesn't have to give much of a zetz to the WR to disrupt either the crackback or the passing route, so he can easily recover to maintain contain against the sweep.
