Regarding DRod and his apparent disregard and ignorance of defense -- I think this is deliberate. In the "unstoppable force versus immovable object" debate, his goal seem to be to have an offense that can score nearly at will, and count on the opposing offense making mistakes, rather than counting on his defense to hold. I'd have to look at stats for his WVU and Tulane teams, but if I find that they gave up 3-4 TDs a game on average, I will not be surprised.
So, his goal is to stack up on offense, hoping that one of the slot dots, 15 QBs and army of undersized backs pans out into a playmaker, like White or Slaton. How many RBs did he take in the Slaton and Gwaltney class? If I remember, it was five or six. All he needed to do was score a hit with one.
Now, it's not a winning philosophy for the Big Ten, but it's a philosophy that works in conferences with weak defenses, and one that can help you catch lightning in a bottle in your bowl game (if you make it that far). You could look at certain eras in the Pac 10, along with the entire history of the WAC, MWC and C-USA, and the post Miami/VT/BC era of Big East football. Obviously, DRod developed his philosophy while coaching in two of those conferences.
It's clear that he's not planning on adapting or changing in any way. scUM truly is WVU Northern Branch, and that's just not going to fly against teams that recruit defense first, like tOSU, State Penn, scUM State, Battery Chuck Madison and Iowhere.
