That's super interesting. Counter-intuitive. I mean if you suck at running, and everyone knows you suck at running, pretending you're going to run isn't very likely to get them to "bite". If you're great at running, and everyone knows you're great at running, pretending to run seems much more likely to get the defense to buy it.FO has looked at the data and found little to no connection between rush rate/rushing success and play-action effectiveness.
That's kind of the idea with ANY fake in ANY sport or endeavor. If your army feints an attack to the left, it's only going to be respected if the enemy really thinks that it's a legitimate threat (i.e., that you can do real damage by attacking to the left). If they're not convinced your attack to the left will cause them any problems, they're not likely to take it seriously and so a fake is pointless.
So I don't really understand how there is no connection, even if that's what the data says.
