Tom and Charlie changed it up mostly due to a suggestion made to Tom by his good buddy Bobby B and went as far as Bobby sending some of his Defensive staff to Lincoln to teach us the 4-3 scheme. Bet ya didn't know that did ya?
So where are the stats about 4-3 getting more sacks?
I seem to recall (memory isn't what is used to be) that Nebraska sought out and went to Florida to get some defensive ideas.
