Ill start! I love running with the Texans playbook. I consider my self a well balanced gamer. I love the running plays as well as the play action passes. I have stuck with this playbook for a while now.
I run with the Saints playbook right now. Tried Steelers then Rams now Saints. I like the two WR sets since I have Larry Fitzgerald and Malcolm Floyd. They seem to have good plays out of all of their two WR sets that allow me to mix up the run and pass well without tipping off my opponent. The running plays work well with a one-cut back it seems. Good ball-carrier vision and good accelleration and you can break some big gainers off. Still trying to learn though.
Washington's PB is the perfect blend of zone running scheme, read option for mobile QB (I have Vick with the Chiefs) and good pass plays. Plenty of play action off good running plays.
