Since I dont personally dont know the man, I have to infer that he is a really good coach, because Bo went outside the sphere of comfort and knowledge to get this guy. I know that he knew someone, who knew this guy, but its not the same, especially for a defensive guy like Bo to hire the guy coaching the most important position on the field (next to qb), he must have gotten some real good feedback and info about this guy. Its a shame to lose Carl, but since we have, I couldnt be happier to have coach Kaz. !!! Its good to have another fireball of passion on this team, especially on defense.
