Might the future of Red Sox broadcasts (maybe not in 2023 but in later years, after Joe Castiglione retires) become a TV/radio simulcast with the joint announcing team doing radio only for preseason games not on TV, nationally televised regular season games, and postseason games (as all postseason telecasts are only televised in a national basis with no locally produced TV coverage)?
NESN and WEEI-93.7 would save a lot of money as each entity would only have to pay half the salaries of the announcers.
However, I think it's been quite a few years since any MLB teams have had announcers simulcast games on TV and radio. I think the late Vin Scully was the last to do a TV/radio simulcast (calling Los Angeles Dodgers games) and before that, I think Harry Carey and Steve Stone may have called Chicago Cubs games on a TV/radio simulcast basis win the 1980's, but I'm not 100% sure.
