Clarify a Couple of Things about Delayed BnR for me

So I understand to D BnR you come out in on PS3 triangle left stick down to bump then square and R2 to flip play is there an easy to make adjustments to a delay bnr play because doing this cancels my reblitzing and zone adjustments if I am not mistaken. Also is there another way to audible into delay bnr I tend to remember something about coming out in man bnr and audible to a zone play might be the other way around though.

I know when I go up against vs Packers or Raiders the D BnR really hurts my O I want to learn how to take advantage of it in my D. I used a bit in 09 with the Packers but haven't used it so long I forget some of the nuances of the technique. Any info or help with D BnR would be great.

Just delay bump and run first, and then make all of your adjustments

its good vs bums not vs people that are good

yeah if someone uses built in motions your BnR wont do anything
