I'd like to agree, but...
My guess is that is a calculated risk.
1.) they're hoping that people will tune in just to see and hear Dan let his biases show,
and
2.) Dan will be on his best behavior to "redeem" himself in the eyes of the viewing audience.
That's not to mention that he has to show fellow travellers that he didn't kill off the network news industry ahead of
time, putting everybody out of cushy jobs.
