Steve Rosenbloom says that for him, "Happiness is being productive. I'd rather work than not work."

He is the owner of 6 percent of the stock in the Los Angeles Rams and an heir to several millions of dollars in a trust fund established by his late father, Carroll.

He is sifting offers to become active in the operation of a National Football League club. Is he ready to invest in a club, or buy one?

"I'm not ready to invest in a club right away," he says. "I would give up my stock in the Rams. It brings income but I have no faith in the people who run them or who won them." His stepmother, Georgia Rosenbloom, owns the Rams and is the chief operating officer.

"I could not buy a club myself," he says, "but I could quickly put together a group to buy one.The money part is easy; finding one available is the hard part. There are none for sale."

He says his attorney talked with his stepmother's attorneys about the possibility of buying her 70 percent of the Rams' stock but was told it was not for sale "at any price."

Stepson Steve says he would sell his stock "but not at a fire sale. If I took that tack, it would have to be in a situation where I might run another club. I could make more sitting on my duff, otherwise."

Rosenbloom attended the Green Bay-Redskins game Sunday at Rfk Stadium. He was asked on Monday if he might become associated with the Redskins, in view of the possibility that Edward Bennett Williams may sell his 15 percent stockholding in the Redskins, since becoming owner of the Baltimore Orioles baseball team.

"No," Rosenbloom said, "they have good people. I presumed Jack Kent Cooke would buy that stock if it became available. I have not talked to them about it."

As to the value of his Rams stock, Rosenbloom said, "I don't know how much a franchise is worth. The last one sold (the San Francisco 49ers) brought about $16 million. The Rams' worth was put at $21 million in the swap of the Colts for them. The Rams now may be worth $50 million . . . $100 million. Who knows?"

There was a recent report that owner Robert Irsay of the Baltimore Colts might be receptive to fresh capital, but it was pointed out that he almost certainly would never sell control because he eventually wants the club to be operated by his son, now a student at Southern Methodist University.

rosenbloom said he did not doubt the ac curacy of the club being unavailable for purchase. As to the prospect of the Colts being reserved for Irsay's son in the future, Rosenbloom laughed at a coincidence. "That's what I was told," he said.
