If I remember correctly, he took a top 5, 3-4 defense, and tried to turn it into a 4-3. His hiring came out of left field (Donahue wanted a newbie that way he wouldn't lose power in BFLO like he did to Cowher in Pittsburg, Plus good ol Ralphie hated to spend money on coaches so he was an easy sell to the owner). The little Nazi comment above makes sense. One of many reasons he didn't get another shot as HC.
