NFL teams committed themselves to what appeared to be more than $100-million in contract extensions Thursday, the last day to sign deals that won't be applied to the new salary cap. Dallas, in addition to signing quarterback Troy Aikman to a record $50-million, also agreed to a three-year extension with tackle Erik Williams. The San Francisco 49ers agreed to deals with nine players. Like the Cowboys, they renegotiated 1993 salaries to increase payments that won't come under the cap. Wide receiver John Taylor got $7.74-million for four years, and tight end Brent Jones got $6.95-million over four years. Cornerback Eric Davis signed for $2.4-million over two years and safety Merton Hanks signed for $2.8-million for three years. Running back Johnny Johnson and the New York Jets agreed to a $5-million, two-year deal with a club option for 1996. None of the figures reflects discounts due to possible deferred payments. Also, unlike baseball, most football deals are guaranteed for only one season at a time. San Francisco guard Derrick Deese received $622,000 over two years, safety Damien Russell $920,000 over three years, guard Ralph Tamm $3.1-million over three years, wide receiver Nate Singleton $687,500 over three years and defensive end Karl Wilson $855,000 over two years. Washington agreed to a five-year deal with tackle Jim Lachey and a three-year contract with wide receiver Ricky Sanders. Free safety Eugene Robinson (two years), linebacker Terry Wooden (three years) and fullback Tracy Johnson (three years) agreed to new contracts with Seattle, while kicker Chris Jacke agreed to a three-year extension with the Green Bay Packers. Free safety Eddie Anderson and kicker Jeff Jaeger agreed to three-year extensions with the Los Angeles Raiders. Cornerback Terry McDaniel and reserve center Dan Turk also got new deals. Kicker Greg Davis and the Phoenix Cardinals agreed to a three-year deal, and linebacker Darryl Talley and the Buffalo Bills agreed to a two-year contract. Safety Anthony Newman agreed to a two-year deal with the Los Angeles Rams. Kicker Greg Davis agreed to a three-year deal with the Phoenix Cardinals, and offensive lineman Carlton Haselrig agreed to a new contract with Pittsburgh.
