On the subject of slowing down the offense, to protect your defense....I still don't understand this logic. Ideally, we'd all love to have an offense that could grind out 10-12 play drives at will. You know, like Texas A&M and Georgia and Alabama did to Auburn this year all game long? Sure, your defense should be plenty rested if your O is constantly doing that. But with a fast paced offense or whatever offense you run, 3 and out is 3 and out. Malzahn wants to run 80-90 plays per game, right? Again, if you're running HUNH or huddling up and running out of the I, your D should have plenty of Twinkie breaks before going back out.
You want to stop people? Don't look at your offense. Go hire great defensive minds and recruit great players and give them a plan to go out there and kick the other team in the ass. You consistently stop the other team with 3 and outs, then who gives a shit what offense you're running. Go pay....err, sign Foster and Liner and Lawson and Johnson and fuck shit up.
