Network television executives were highly skeptical of the Carter administration's concept of financing alternative games to the Moscow Olympics through the sale of television rights.

New York spokesman for ABC, NBC and CBS Sports said they had been approached about televising such games, but had not received proposals specific enough for them to decide if and how much they might bid for broadcast rights.

Official comment was generally noncommital, but, privately, executives at all three networks expressed serious doubts about the administration's ability to organize alternate games on short notice, and about American television's willingness to pay substantial rights fees for the games.

One executive called White House counsel Lloyd Cutler's Geneva comments "ridiculously niave."

A colleague at another network said, "They have suggested holding these games every place but Disneyland, which would be the best site since the administration is obviously living in a fantasy world."

"It's sheer speculation to say that TV rights would pay for the games, because they don't appear to have considered many of the important factors involved -- existing program commitments, the availability and cost of satellite transmission, the quality of the games in question, and the painfully short time for organizing and selling all this," said one executive, who described the administration's efforts as "extremely clumsy."

It would be particularly difficult and costly to televise games from several sites on different continents, as the administration has proposed, network sources said.

Games starting in mid-September would also post almost insurmountable problems for the networks, sources said, because they would clash with the end of the baseball season, the beginning of football season, and the new television season.
