The majority of CB wanted Bronco to stay. There was a vocal minority that wanted him to go. Evidence this 2015 poll on Bronco vs. Sitake:

I think most would agree that Tuiaki is far worse than Kalani would be at DC. Just because a few people on CB say something stupid does not make it consensus.
Bronco has been patient and worked hard to coach up Nick Howell. He would be worse without Bronco there backing him up.
