‘New England’s base defense is the 4-3, but the Patriots will line up in more diverse fronts on all downs more than most teams. Against the Bills last season, they used some “bear fronts” as a way of clogging the running lanes for LeSean McCoy. The Jets successfully used similar condensed fronts, with a head-up nose tackle flanked by two linemen squeezing in the middle in 3-technique positions.’
