then i'd start to slowly transition. It is very easy to use 4 man front in the nickle whether you have 2 true de or 1 de and 1 stand-up olb. One thing i'd like to see is a "racecar" package where in nickle and dime scenarios they have pass rushing d-ends move in at tackle and have 4 speed rushers getting after the qb. I'm sure they'll mix in lots of different ideas and find what works best with the personnel they have.
