Turnovers Remain Flaw for Raiders : Pro football: They throw three interceptions and lose to the Cowboys, 13-7. Dallas plays without Aikman and Smith.

The names have changed.

But not the numbers.

Or the outlook.

The Raiders of 1993 look all too much like the Raiders of 1992--too many turnovers, too few points.

In losing to the Dallas Cowboys on Saturday night, 13-7, to drop their exhibition record to 1-2, the Raiders continued to show the same alarming tendency to self-destruct that caused them to suffer through a 7-9 regular season last year.

For the second consecutive week, the Raider offense threw the game away with several crushing interceptions.

That offense has now failed to score in eight consecutive quarters.

The only Raider points before a Texas Stadium crowd of 60,411 came from the defense.

On the final play of the first quarter, Dallas quarterback Hugh Millen passed to running back Derrick Lassic on the left side for a two-yard gain.

Linebacker Winston Moss threw his arms around Lassic, springing the ball loose. Defensive back Terry McDaniel picked it up and went 28 yards untouched into the end zone.

The Raiders spent the rest of the night making one futile attempt after another to get back into the end zone.

“Our offense moved the ball very well,” Raider coach Art Shell said. “Very well. We’ve just got to get it into the end zone. We are too good a football team not to get the ball into the end zone.”

Actually, the Raiders didn’t move the ball all that well. They were outgained in total net yards, 365 to 238, in passing yards, 233-139, and on the ground, 132-99.

The one statistic the Raiders dominated was turnovers, with three to one for the Cowboys. That gives the Raiders an 8-2 edge over the opposition in turnovers in the last two weeks.

Quarterback Jeff Hostetler threw one interception and backup Vince Evans added two more in the second half Saturday.

That has to be particularly galling to Hostetler, who has thrown three interceptions in two weeks. He threw only three all of last season with the New York Giants.

But in the locker room afterward, Hostetler seemed almost upbeat.

“No question about it,” he said, “we moved the ball upfield. We’re putting it together, piece by piece. But it may not be fast enough for some people.”

It didn’t help that kicker Jeff Jaeger missed two field goals, one from 54 yards and the other from 45.

But the biggest problem for the Raiders is the offensive line, particularly left tackle.

That was thought to be a strength this season. The Raiders signed free agent Gerald Perry of the Rams, and installed him at left tackle. But Perry suffered a torn tricep and has sat out the last two games.

So the Raiders moved Greg Skrepenak over to tackle from the guard position. But Skrepenak suffered a dislocated joint in his left ankle in the first quarter Saturday when he backpedaled into Hostetler while trying to fight off Charles Haley. Skrepenak is expected to sit out at least eight weeks.

Also injured Saturday was veteran guard Max Montoya, who had to leave because of a sore ankle. The Raiders filled in with Rich Stephens at tackle and Todd Peat at guard.

The Cowboys were playing without quarterback Troy Aikman, who is recovering from offseason back surgery, and holdout running back Emmitt Smith.

But they still managed to even their exhibition record at 1-1-1 on Lin Elliott field goals of 28 and 24 yards, a 41-yard touchdown pass from Millen to wide receiver Jimmy Smith and 91 yards rushing by Lassic.

Raider Notes

Veteran defensive lineman Howie Long, who ended a 25-day holdout earlier this week, did not play. Coach Art Shell said that he did not want to start him out so soon on artificial turf. . . . Quarterback Todd Marinovich did not see any action.
