They use the extra wr to block the de, or lb on the backside. Just enough to force the defender wide, giving a cutback lane if needed. This allows the RB to get to the 2nd level facing that cb who followed the wr in the box. Linehan uses this too much IMHO.
Thanks for the description.
I'm not convinced by the tactic, though. Sounds like you aren't either.
Seems like a block destined to fail more often than not, with the advantage to the defender who is larger and stronger than the WR, and now you've crowded the box with two more players.
They would do this with Beasley and Austin. How are they supposed to be winning against DEs and LBs?
The tactic is a bit more credible with Noah Brown. He at least has some reasonable chance to block bigger guys. But if you're the defense, wouldn't you actually match up a LB against Brown, since you're not worried about his receiving at all? Or at least a big safety? He's not running away from anyone. And now you're bringing a credible run defender into the box.
Still don't like it, but the switch off is trying to do something. I just doubt it works that well. I'll have to look for it next game.
