The schemes run by these two coaches are bi polar opposites. It was just not a,change of Coordinators but a complete change of philosophy on how to play defense.
Diaco- wanted bigger athletes, played 2 gap up front, limited fronts, limited blitzing, limited coverages, limited substitutions kept both safeties deep 80% of the time, was willing to surrender yards and 1st downs but got stingy in the Red Zone. As,a result of the zone pass defense you create more interceptions because your eyes stay on the QB the whole time.
BVG- needs quicker athletes, plays one gap up front; multiple fronts, multiple coverages, blitzes often, uses multiple substitution packages, spins down his safeties often and does not want to surrender any yards or first downs. As a result of all the man for man defense and blitzing, you should get more tackles for loss but fewer turnovers.
Diaco was criticized and accused of being vanilla, bend but don't break and too passive.
BVG- is being criticized because the defense breaks down and gives up tons of explosion plays.
Truthfully the DC's that can "blend" those two philosophies with good players have produced the best defenses. Kirby Smart, Luke Fickell/Chris Ash, Vic Fangio, Jeremy Pruitt, John Chavis, Pat Narduzzi and Dave Arranda.
ND has to get back to being more proficient at "playing it safe".
