Yes! I swear post routes are NEVER open (to your outside guys). If my WR is running a post, it's always the same drill: He's my first read, he makes his cut, he doesn't separate. And it doesn't matter because the safety is waiting in his path anyway. Oh, and a linebacker will generally be floating somewhere back there, making it difficult to touch it over him and easy for the safety to come over. Hey, but look, either my TE or my slot receiver is running all by himself over the middle.
