There's a lot that goes into schemes and after the fact that Butch has been a 43 guy at every stop, and Shoop is a 43 guy (my preferred Defense) there's some other details that I'm not 100% on w Shoop.
He likes to run more zone in the secondary with a lot of zone blitzing. According to Doug Matthews that is.
I like man coverage at all costs.. And he said he would ask him about this(zone/man) Sunday if he's on his show. Said he wasn't bringing anyone from former staff and is joining a defensive staff that primarily ran Man and has been together for years. Wonder how that will play out.
I personally cannot stand zone defense. But in some cases may be necessary if your personnel is suited for that.
