This could be it, the final broadcast for Tim McCarver on Fox. Once the World Series ends, so will Tim’s career at the network, and for those who work with him closely, the moment is difficult to accept.
Ken Rosenthal of FOX just wishes people could have seen how diligently Tim prepared, not just for postseason games, but every Saturday broadcast for a quarter of a century. Someone who after retirement transformed himself not simply into a former player turned analyst, but a broadcaster skilled enough to co-host primetime coverage of the 1992 Winter Olympics.
Joe Buck, 44, is 28 years younger than Tim, yet their chemistry in the booth is natural, always has been, in part because they share a deep, mutual respect, and it’s going to be difficult for someone to fill his shoes.
