Still think we mostly agree. There was something wrong with Miami's screen game that is separate from box count. Poor blocking? D reading the play call? Personnel? I don't know, but if the box count says the screen is the best play and results show it's one of the worst plays, there is something wrong somewhere. One more time . . . in general I'm a fan of the screen. It has a number of advantages. But when the math says it's a good call and the results say it was a bad call, something is wrong. My vote goes to frequency of the call and (lack of) blocking.
Screens, flares, draws, traps, play-action, and the rest of the gimmicks are constraints when a defender or the defense cheats. It's the only time they should be used. 8 in the box doesn't constitute as that if they are still playing disciplined. It's really that simple.
Screen plays as part of your system will result in failure which is why we are so ineffective with them.
