Just because someone is on the weekends, it doesn't always mean it's a demotion. KTLA's Lynette Romero has co-anchored the KTLA 5 Weekend Morning News for quite some time now. Most will remember, Lynette was brought in from Denver to co-anchor weeknights with the legendary Hal Fishman. That pairing always seemed odd and the chemistry was weird. For many years after she was moved off of weekday nights, Lynette served as a GA reporter (which she does a great job). She found her stride again as a strong anchor on the weekends where she can show her personality. She's also a great fill-in on the weekdays when the A/B anchors are out.
Also, lets not forget Kathy Vara at KNBC. She was brought in during the mid 1990s to anchor next to Kent Shockneck on Today in LA. They were a strong team for many years. They domimated ratings at the time as well. Kathy left for KABC for a short time and has since returned to KNBC as weekend co-anchor. Again, Kathy does a fantastic job and knows the market. She's been a great go-to person when news breaks on the weekend (OC church shooting earlier this year). Should Colleen Williams retire or Carolyn Johnson choose to move on to something else, Kathy would definitely be the #1 choice to fill either seat if I were the ND.
