 Yeah just keep this mind, I'd still try the ravens book out but we all kind of have a nemesis built into the game just because of how we scheme our team.  I like physical db's and big boy lineman which helps against most teams but if somebody is good at throwing the ball its my weak point, I've built that weakpoint into my scheme.  Just know that some schemes are your kryptonite, dont blow up the team completely trying to stop one scheme if yours is working against everybody else.
