Are broadcast journalists and NBC network execs skeptical about Brian Williams upcoming stint on SNL? Possibly!

But not Jeff Zucker, who gave Williams the okay (possibly because he has some "influence" over at 30 Rockefeller Center) and Tim Russert, who considers it "an honor for this news division" and, coincidentally, is Williams co-moderator for the Democratic debates.

Frankly, we'd be more interested to hear what Katie Couric thinks about all this. But strangely, after that whiny interview she gave to NY Mag a few months back, she's been letting her third-place ratings do most of the talking.
