With regards to holding....dropping it super low just doesn't work like it did prior to patch three (not this week's patch, the one before it). I can't explain why, but it is really working well.
I toyed around briefly with bumping up offsides and false start and something about the dynamic felt
off to me. I'm not done testing it yet; but honestly, I really like what I am seeing with this current setup. Pressure is there, the CPU still runs very well and the user run game is more challenging (particularly when using a poor line). An offset like you suggest could work, but I just don't know if it is necessary - I just need more time.
I am currently running a fantasy draft (letting the CPU pick all of my players)...hoping I get a crappy team drafted for me
. Once that is done, I am going to try to dive into a CFM and try to get through a few games to see how it goes before changing anything further.
