And in Jeff's case, I think pvi knew Gary Papa wasn't gonna be on air much longer, and rushed to get another anchor. However with that said, they very well with Roberts & Grow leaving around the same time rush for a cheap replacement.
I still don't think Mosley will be back however. When at pvi she never really advanced at the station. She started on weekend weather, and was passed by in the peaking order by both David Murphy (started as weekend morning weather person, although overall he had more seniority when you count his reporting days) and Karen Rogers (started on Am Philadelphia/Live & then did weekend morning weather). She also had very few general assignment reports. Erica Grow for example has a few each week. Last, but not least she almost never filled in for Dave Roberts / Cecily Tynan. They use to always have Karen Rodgers or David Murphy fill in. Then when Adam Joseph came he would fill in. Even Erica Grow has fill in during the main 6 & 11 broadcasts many times.
Overall, even when she was there I always felt that she was the black sheep of the pvi weather pool. So I doubt she is someone they would seek out. However I could be wrong.
