How many talking heads are needed to take over for Vin Scully?

Not one, certainly. Apparently, not two either. Three seems likely, although often there are actually four.

One year, much too soon, Vin Scully will retire and the Dodgers will face the unpleasant task of replacing the most legendary announcer in Los Angeles history.

But if you want to get a glimpse of how the Dodgers are considering how to replace him, all you have to do is pay attention to this season.

The Dodgers hired five new broadcasters in the off-season -- Orel Hershiser, Nomar Garciaparra, Jerry Hairston Jr., John Hartung and Alanna Rizzo -- to help trumpet the arrival of their new super-secret TV network and to complement their radio broadcast.

So who is proving their No. 1 radio color voice when Scully is at home during road games outside of California and Arizona?

Kevin Kennedy.

Yep, Kennedy, who’s not even listed as a team broadcaster or color man. He’s the co-host of the radio postgame show. Apparently, five new faces were not enough.

For the last few weeks, Kennedy has been doing color alongside Rick Monday on the radio, while Garciaparra moved into the TV booth with play-by-play man Charley Steiner and Hershiser. Now they have three guys trying to talk at once, except when Rizzo joins them for more of a newsy update, and then they have four.

A source familiar with the situation said that is the plan for the rest of the season. The Dodgers like this three-headed TV announcing crew thingy.

Which means the 70-plus percent of us in the greater Los Angeles area who do not subscribe to Time Warner Cable, cannot view games on SportsNetLA and want to at least listen to the game live will have Monday, and presumably Kennedy, on the radio.

The Dodgers warned us at the beginning of the year that this whole broadcasting crew would remain in flux as they sorted things out, and they weren’t kidding.

I would love to provide an opinion on how three talking heads in one booth are working out, but I’m of the 70% who’s never heard a word of it. Kennedy is knowledgeable and a voice of non-slick reason on “Dodger Talk,” but he doesn’t exactly provide variety when teamed with Monday, both being ex-players in their 60s. They agree a lot.

But TV clearly comes first for the Dodgers these days, even if only a small percentage of those in the L.A. area can watch. Hey, one day.
