If you were going to construct an NFL, team. Isiah Robertson and Larry Gordon might well be the outside linebackers; Cody Jones certainly would be a fine defensive lineman and Gary Fencik, Mike Williams and Dave Elmendorf splendid defensive backs.

On offense, how could you turn down runners Delvin Williams and Wayne Morris? Or y as the wide receivers?How about Johnny Rodgers as a kick returner? And Steve Pisarkiewicz as a young quarterback with fine potential?

George Allen did not exactly turn them down. What the Redskin coach did was make it possible for them to be of enormous value to other NFL teams. Their common thread is being once-anonymous draft choices Allen traded during his seven years in Washington.

As near as can be determined, Allen has swapped 62 draft choices that other teams have converted into live bodies. Most have been such as Art Meadowcraft. Buzzy Lewis and Mike Zikas, probably solid citizens but hardly timber from which to construct NFL titans, or even Titans, you AFL diehards.

Nearly one of every five draft choices Allen has peddled from Washington has become a useful player, however.In fact, most are starters. And a few - the Rams' Robertson, the 49ers' Williams and the Colts' Doughty - would enhance many All-Pro teams.

Just last week, for instance. Wayne Morris of the Cardinals and Williams were fourth and fifth in rushing in the National Conference. The Chargers' Rodgers was sixth in the American Conference in punt returns and another seemingly harmless draft pick, now cornerback Lee Nelson of the Cards, has four interceptions.

Some might insist this perfectly illustrates the long-term folly of the Gospel According to George Allen, that one cannot continuously trade away the foundation of a franchise for lots of elderly patches. And two NFL executives did get a long laugh out of the results of this research.

However, those very executives have not made the playoffs lately. Allen's teams have been there five of the last six years. And weak as they seem in relation to at least six teams at the moment, the Redskins still have a chance again this season.

What all this proves is that nobody gets anything for nothing in the NFL trade mart, that Allen might have you believe he has slickered his peers time and again but anyone with the time and inclination knows otherwise.

Allen formed the foundation of his defense in a 1971 trade with the Rams that brought diron Talbert. Jack Pardee and Myron Pottios. Two of those traded draft choices because Robertson and safety Elmendorf.

Allen made a seemingly tame deal with the Cards, getting Fred Sturt and Jimmie Jones for a fifth-round draft pick in 1976. That pick became Wayne Morris. Also in '76, the Lions got Hill with the pick from San Diego the Redskins gave up for Duane Thomas.

Cornerback Williams was chosen on the first

Rodgers was chosen on the first round of the 1973 draft, with a choice San Diego got through Baltimore in the Roy Jefferson trade. The Colts used the other choice in that trade. The Colts used the other choice in that trade for Doughty. In 1974 the 49ers drafted Williams with a second round choice from the Redskins obtained in a trade for Rosey Taylor.

Still, the Rams seem to have benefited most from trades with Allen. In addition to Robertson and Elmendorf, they got Waddy and Cody Jones with draft picks from the Redskins. In truth, draftees acquired from the Packers, Redskins and much of the Ram team was developed with Eagles.

In addition to their deals with two Redskins - the Rams used first-round draft picks from the Eagles - for Roman Gabriel - for runner John Cappelletti and guard Dennis Harrah.

From Green Bay in exchange for quarterback John Hadl, the Rams drafted defensive lineman Mike Fanning and used another first-round pick to give Detroit for wide receiver Ron Jessie. Also, they chose cornerbacks Monte Jackson and Pat Thomas and rookie saftety Nolan Cromwell.

"We call that our Lawrence Welk deal," said the Packers' publicist Chuck Lane, "You know, a one and a two, and a one and a two and a three."

Allen has won his share of victories over rival traders, of course. His best was getting Billy Kilmer from the Saints in 1971 for draft choices that became center Wimpy Winther and defensive back James Elder.

Second best was the Ron McDole trade with Buffalo. It is not certain what Allen surrendered for that wonderfully durable end. He has given the Bills six draft choices over the years, though, and none of the players selected is still in the league.

Allen was the biggest loser in the Thomas deal, although with payment for Dave Butz and others still due the worst may be yet to come.
