Yes and no...at least they shouldn't be, yet. I think if they were going to lose the demo by a much wider margin, they might not have tried such a move, not to admit defeat, per se, but because they knew it would be an insurmountable lead. This last-ditch effort strikes me as a quick, easy-to-throw-together attempt to make up the difference. If it worked, great, if it didn't, so be it.
Again, I'm still trying to figure out why this is such a big deal. NBC 5 has pulled off a few sweeps demo victories in the last several years, and it hasn't gotten this kind of press. I still maintain that this isn't going to be very notable until WMAQ strings a few of these together. THEN ABC 7 can worry.
Either way, renewed competition is a good thing.
