Yeah, probably an oversimplification but still a good data point about the personnel change. As you state, some games we are going to shoot great while other we might not, kind of the nature of our offense, particularly one that relies a lot on the 3 ball. But having a good tough defense allows us to stay in every game though.
Also, Georgia State got a lot of garbage time points against our walk-ons in the last few minutes. Their final score was not indicative of how much our defense controlled that game.
I know this is a football saying but defense wins championships. If you play good D, you more than likely are controlling many facets of the game, even games when your shots are not falling.
