Tony is a short term solution to a long term problem. Getting rid of Scott was a huge mistake, having him lead the network through the events that unfolded in the first couple years following would've been helpful. Norah having these behind the scenes "meltdowns" and all the drama is a serious problem for the network and will eventually be a PR issue, we've watched her get angry while she's live on the air, imagine how she acts when the camera is off.
Brian Williams would be great but I'm not gonna hold my breath.
My suggestion, Ann Curry, she has the experience, look, presentation and leadership. Best of all she's no drama and very straight forward, she would bring in good interviews and stick around long enough for CBS to groom a long term replacement, just 5 years would be long enough for them. She's also been out of news long enough to be viewed as an outsider who isn't caught up in politics and she's no longer immediately associated with NBC & Today, not to mention all the people who would be rooting for her comeback.
I use to watch Scott every night, the transition to Jeff was weird and people got too comfortable with Anthony Mason.
I haven't consistently watched Norah at all and never will.
Bringing Scott or Jeff back would be better than what they have now.
