Guds already got himself involved in the play when Campbell was a good 5+ meters away from the bench (seriously, how is that Campbell's fault? he's not the one that decides to cheat, that's either on Madden or Guds himself) and like I said, it would have been a penalty regardless of whether Campbell hustled or not. Guds is involved in the play from the very moment he steps on the ice, that's a clear cut too many men on the ice, even if Campbell had been closer to the bench.
For us to blame Campbell on that, Guds would have needed to remain on the bench while Campbell went for the change, thus causing an odd-man rush and a potential scoring chance.
