Oft-injured Phil Simms, who stayed healthy last season and guided the New York Giants to the playoffs, yesterday signed a five-year contract reportedly for $3.8 million, making him one of the NFL's highest-paid quarterbacks.

The deal could reach $4.5 million if Simms achieves all the incentives written into the contract, a source close to the quarterback said. According to Simms' agent, there is no deferred money in the deal.

Simms completed 286 of 533 passes last season for 4,044 yards and 22 touchdowns . . .

Negotiations between the Chicago Bears and William (The Refrigerator) Perry hinge on some weighty issues -- namely whether the massive rookie will trim down enough to play this season.

Agent Jim Steiner is pushing for a deal between the $1.3 million offered by Chicago and the $2 million-plus deal linebacker Wilber Marshall received when he was the Bears' No. 1 pick in 1984.

Steiner said the Bears want to base one-third of the contract on a "conditioning clause," which would pay Perry according to his physical condition, endurance, strength and percentage of body fat.

Steiner said these conditions are appropriate for Perry, who weighed more than 350 pounds in February and was down below 320 in May.
