What we need is a new CBS nighttime show to fail so bad, that they don't even air the rest of the episodes, and instead fill that time with Price.
And even that may not be enough.
While I would like to see more Price, I think it's short-sighted to root for CBS primetime to fail... in the long run, stability at CBS is good for the show, and instability at CBS is bad. If CBS is in a position where they're
so desperate that the only option they have to bail them out in primetime is Price, I would take it as a very bad sign for the network.
Price is Right is a band-aid for short-term fixes, but there is no reason to believe it would be a serious ratings contender against most primetime stuff. Even Bob's regularly scheduled MDS's usually were usually slotted in Friday and Saturday nights where there was almost no real competition.
If a show fails in the way you've described, in a timeslot where CBS presumably thought they would be competitive, it would leaves a gaping wound in CBS' schedule. The band-aid Price would provide isn't going to do much to fix that. There's plenty of other options they should be considering to fill that gap before they reach for the box of band-aids...
ABC's shows are doing okay, but they're certainly not immune to serious counter programming. They do well enough when paired against reruns, but they struggled towards the end of last season once things like Big Brother started, and something like an NFL game eats them up and spits them out.
