UPDATED: Why The Deep State Needed Flynn Gone So Bad
The reason Flynn had to go was because if he once settled in as NSA he would soon discover the whole operation against Trump--not only against the campaign but the continuing operation, centered in the NSC with Obama holdovers. Flynn would have been just about the only fully professional intel specialist, and at the top of the heap he'd see it all. With Flynn gone, in point of fact, the Obama holdovers at NSC and USIC were actually able to engineer the fake impeachment.
J. E. Dyer offers three brilliant tweets to explain this:

They had to intercept @GenFlynn quickly, b/c *the NSC was ground central for the anti-Trump op.* That's what I'm not sure everyone gets yet. It had to be executed at a level above auditability. Neither CIA nor DOJ qualifies...

And once they had to brief him about all ongoing counterintelligence cases, and Flynn dug into this, he was going to INSTANTLY see what they had done.
He would’ve quickly determined they’d BLUFFED their way to a surveillance warrant approval on Carter Page by using FRAUD.

Only level effectively unaudited over time is *NSC.* NSC is where only real check is what POTUS will either protect or weed out. And it wasn't just records of what HAD been done. They wanted to keep it going under new admin. We know they tried w/extensions of Page FISA .... 2/3

Mueller SCO was same effort. Flynn wd have detected whole ball of wax; he had to go. In retrospect, planning decision on that made right around 25 Dec 2016-4 Jan 2017. Hence keeping Flynn case open & moving to (1) ICA/dossier maneuvers (2) "leak" to Ignatius & follow-ons. 3/3
Now, listen to Andy McCarthy explain it at a bit more length--best thing he's done in ages:
Durham is going for the whole ball of wax. So much more than what most people think. "Sprawling"? God help us!
UPDATE: I just finished listening to the Lou Dobbs interview of Sidney Powell. It was an extraordinary, powerful, emotionally charged presentation by Powell--speaking as forcefully and openly as she has to date. Toward the end of the interview she sets out the key dates in January, 2017:
January 4: Strzok intervenes to keep the unpredicated Flynn case open, despite the fact that the Washington Field Office has found nothing against Flynn.
January 5: Obama summons the coup plotters to the Oval Office--Susan Rice, James Comey, James Clapper, John Brennan, Sally Yates--to strategize on the way forward, specifically discussing Flynn.
January 6: Comey is dispatched to New York to intimidate Trump by telling Trump that they have dirt on him--an attempt at blackmail that Trump angrily rejected.
January 10: Clapper tells "journalist" David Ignatius at the WaPo to "take the kill shot" on Flynn.
January 12: Yates and Comey sign off on the first Carter Page FISA renewal, to continue the spying on Trump.
