It is impossible to determine if Butler will be an improvement or not in the summer. White called the defense last year. You can try and blame Butler for the passing defense if you want, but he coached DBs, he didn't make the calls. Sacks per game declined from 2023 to 2024, was it a lack of blitzes or was it because the front didn't get pressure and left the DBs covering for longer?the discussion we're currently having on whether Butler will be an improvement, the same, or he was the reason the defense went from 47th in opponent completion % in 2023 to 107th in 2024, or from 37th in total passing defense in 2023 to 64th in 2024.
Rush yards per attempt went up nearly half a yard from 2023 to 2024, was this because the DL didn't get off blocks? LBs not in the right fit? DBs playing more man with their back to the play? Over agressive Rover and LBs?
Big Plays, 10 yards or more, went up from 190 to 240 - Pays for 20+ yards went up from 64 to 84. Was this because of Butler's influence? Did White call more blitzes? Did Nebraska get caught in man coverage? Did the LBs miss their run gaps?
It is simple to blame Butler's arrival and then later Snow taking the analyst position. I think White's defense was predictable at times, conservative at times, and there were times when White did not or was not able to adjust to the opponent's adjustments.
Boston College -6 after the half
Iowa -13 after the half
USC - 8 after the half
Indiana the whole game
Illinois -14 after the half
Then the win against Colorado -10 after the half.
Not all of that was on the defense, the offense went way to conservative as well. especially Colorado, Iowa and BC.
