Admittedly only know a little football myself so help me out with a few things

brotha ...
1) Was Diaz free to tweak what UM did defensively to better fit his personnel or was "Manny's defense" the only available option?
2) What level of responsibility does Diaz hold for the linebacker play, which, as you indicated, seemed to get worse instead of better under his watch?
3) How much (if any) of the blame for the inconsistent effort, shoddy fundamentals and bone-headed mistakes we all saw from our defense over the last several years lies with Diaz?
4) If it's simply having the "right kind of players" to make Manny's scheme work, would James Franklin have been better served hiring a recruiting savage to run Penn State's defense instead of a guy who lost his job at Texas and Miami because his units couldn't stop a nosebleed?
