No. The IG report says, and the FBI acknowledged, that the Steele Dossier was "central and essential" to the FISA applications. The supposed communications with Russians they cited were from a Yahoo News article that the FBI did not even bother to verify. The Yahoo News article was put out by Christopher Steele.
They didn't get the first FISA until they had the Steele Dossier, and the Yahoo News piece to "back it up".
They knew Carter Page worked with the CIA since at least 2009- they had met with him in the FBI's NY field office, they were aware that he was a CIA source. It was only in 2016 that they decided he might be a Russian agent.
They knew by January the Steele Dossier was garbage, but they continued to use it for 3 more FISA renewals.
Banana republic bullshit.
