Gubb says they all know what's expected under McFadden and Doyle's leadership, and the club's action against the six players proves there are consequences.
"The culture that Jim and Cappy (McFadden) want to set, we know the rules and you've got to stick to them," said Gubb.
"We always have a team meeting in the morning and there was just a different feeling. We went in and Cappy just told us straight up what was going on.
"The boys didn't meet some standards and to create the culture that we want you've got to be disciplined and if that means dropping some of your best players then you've got to do it."
Gubb acknowledged these incidents of ill-discipline, together with the team's inconsistent performances, fuel the public's perception the players don't respect McFadden, who is under huge pressure after achieving three wins in their last 16 games.
Gubb refutes those claims but accepts the only way that perception will change is by performing on the field consistently.
"People assume things and we're not doing him any favours by playing the way we did," he said. "What hurts the most is people blaming Cappy because, as a team, we've got so much respect for him and he's a great coach.
"We just need to start delivering for him because it's easy to point the finger at the coach and also the star players cop a lot [of criticism]. The only way we can stop that is by winning."

Gubb said the players already expected some changes were likely to be made for Sunday's must-win game against the Dragons at Mt Smart Stadium in the wake of their embarrassing seven-tries-to-none defeat to the Storm.
"Probably not to this magnitude but there were definitely going to be changes."
