The Washington Redskins are planning to renegotiate quarterback Jay Schroeder's contract this spring to make his salary more comparable to those of other starting quarterbacks in the National Football League.

Schroeder reportedly made $155,000 last season and is scheduled to make $215,000 in 1986, the final season of a three-year deal he signed with the Redskins. That contract was negotiated when Schroeder was a third-round draft choice who had started only one game as a quarterback at UCLA.

Joe Theismann, the Redskins' starter until he broke his leg in November, made $405,000 in 1985, according to the NFL Players Association. He recently signed a new two-year agreement with a bonus, but those terms remain undisclosed.

A list of other quarterbacks' salaries indicates that even Theismann was on the low end of the scale.

A sampling: San Francisco's Joe Montana made $900,000 last season; Denver's John Elway, $800,000; St. Louis' Neil Lomax, $650,000; Chicago's Jim McMahon, $600,000 (plus a $350,000 bonus); Dallas' Danny White, $550,000; Philadelphia's Ron Jaworski, $400,000, and New England's Tony Eason, $325,000.

"Obviously, there's been a change in Jay's situation," said Marvin Demoff, Schroeder's agent. "He's gone from being a baseball player in Class A ball to being the Redskins' starting quarterback. Obviously, the subject [of renegotiation] will come up between now and the time training camp starts.

"Everybody realizes to change Jay's contract is the equitable thing to do," said Demoff, who would not discuss specific salary figures.

It's likely any contract talks would include discussion of an insurance policy for Schroeder -- against the possibility of a career-ending injury. It is believed Theismann has such a policy, which he took out before his injury.

Redskins General Manager Bobby Beathard was out of town and could not be reached for comment, but the plans to renegotiate were confirmed by a source within the Redskins organization.

Schroeder led the 10-6 Redskins to a 5-1 finish after replacing Theismann.

"They've talked to Marv," Schroeder said, "and they've said that eventually, they'll talk . . . But I'm very happy with what I'm making. In fact, I never dreamed I would be making this kind of money."

Schroeder's position as the Redskins' apparent No. 1 quarterback was strengthened considerably last month when Beathard said the Redskins had talked to four teams about trading Theismann, their starter since 1978.

Although no deal has been struck, it has become clear that Theismann and the Redskins are seeking a trade to avoid a potentially divisive quarterback battle at training camp this summer.

Theismann has not returned several phone calls to his office.

Demoff said he expects to have "low-key" discussions with the Redskins sometime after the NFL draft April 29.

"It's never a situation that will heat up," Demoff said. "We'll either change [the contract] or we'll live with it. Jay would never demand more money. He really appreciates the situation he's got with the Redskins."
