The pass covered 65 yards and settled into the hands of receiver Morris Bradshaw for a touchdown. With that thrown by Dan Pastorini last week against New England, the Oakland Raiders knew the bomb was back in their offense.

For the last few seasons, as quarterback Ken Stabler's arm grew weaker, long passes became a seldom-used Raider weapon. Stabler was much more comfortable dropping off balls to his halfbacks or concentrating on medium-range tosses.

The same cannot be said of Pastorini, the live-armed thrower from Houston the Raiders obtained in a controversial offseason exchange with the Oilers.

Pastorini loves to go deep as much as he is permitted. So fans attending Saturday night's exhibition game against the Redskins at RFK Stadium should be treated to some long-distance tosses, the kind seen infrequently in the Washington offense.

In two exhibition games, Pastorini has demonstrated he will fit nicely into Oakland's offense, which now also includes running back Kenny King. King came to the Raiders in another trade with Houston that saw Jack Tatum go to the Oilers.

King, who did not carry the ball for the Oilers last year but was a standout at Oklahoma, is competing with Arthur Whittington for the No. 1 halfback spot. Whittington gained 397 yards last year, second to Mark van Eeghen's 818.

Pastorini has speed at the wide-reciver position with Bradshaw, coming off a knee injury, and Cliff Branch, who had 59 receptions for 844 yards in 1979. aDave Casper (57 catches) is the tight end. Casper's backup, Raymond Chester, who retired briefly, is in camp but probably won't play.

Now that Tatum is gone, the Raiders have Mike Davis and Charles Phillips as their safeties. But Phillip has a knee injury and Burgess Owens, who was obtained from the Jets, is currently at his spot.

The Raiders have played both a three-and four-man front in the preseason. Much of what they do in the future could depend on the development of rookie Matt Millen, the No. 2 draft choice from Penn State. Millen, a defensive tackle in college, is pressing Monte Johnson for a starting middle linebacker spot.

Quarterback Marc Wilson, the top draft choice, showed well last week against New England. He presently is third string behind Pastorini and veteran Jim Plunkett.
