Scully was Barber's protege.
I never heard Barber or Allen, but I never heard anyone better than Scully. He doesn't let chatter or ego interfere with calling the game.
I LOVE Vin Scully. I discovered him rather late, thanks to the MLB package, and during a couple of fairly recent trips to LA.
I'm a Red Sox fan living in Connecticut, but when we get a Dodgers game on Prime Ticket with Vin Scully, I often watch the entire game. (So I've seen lots of Red Sox and Dodgers games!) I just love listening to him.
If MLB decides to give us the broadcaster from the team opposing the Dodgers, I might watch an inning or two, but that's it. Nobody around today beats Vin Scully, IMO.
