O.K., let's make it official. The Washington Post sponsored Redskins-Jets exhibition in RFK will mark the long-awaited Sonny Jurgensen Day, by mutual consent of the old pure-as-gold passer and George Allen. So it itsn't a regular-season game, it's for worthy causes, is your last chance to see the 'Skins before the opener, and Joel Margolis promises to do the Sonny ceremonies up right. Even the date fits in: Sept. 9. Good ol' No. 9 . . . That's a Friday night game, and can anyone believe the gov't won't find the money to open the Metro subway to the stadium after hours? Let alone Redskin Sundays? If there was any doubt, the Metro link to RFK will be inaugurated at 10 a.m. this Thursday by - George Allen . . . The same Allen has done it again as head of Summer Jobs for Needy Youth in D.C. - with more than 40,000 placements, tops in the nation a sixth consecutive year . . . In Chicago, where the NFL Players Association hatched plans this week to form an abuse-clearing association of sports agents and lawyers in concert with the baseball, basketball and hockey players, NFLPA director Ed Garvey said of the owners-players settlement, "We're easing into this peace." To which Redskin Len Hauss, a union leader, cracked: "It's boring" . .

You can bet the State of Maryland was rooting for Seattle Slew yesterday. Of $140,000 in winning Preakness tickets unclaimed, $50,000 worth figured to stay unclaimed as souvenirs if Slew became a Triple Crowner - the money reverting to the state in a year . . . As UCLA basketball coach Gene Bartow gradually edged off the seat he knew would be hot but not this hot, predecessor John Wooden offered, "Gene was definitely too sensitive. He always has been. I'm not saying that in a critical sense. It might be one of the finest compliments you can give a man. But . . ." Would Wooden, who at 66 jogs five miles on the UCLA track each day, consider a comeback should Bartow leave? "Oh no, I'm retired. When I retired from coaching I retired" . . . Jesse Owen's opinion that Texas' super sprinter, Johhny Jones, should give up football drew from Longhorn track coach Cleburne Price, "I think he'd be crazy to quit football." Price knows which side of athletic director Darrell Royal's bread to butter, Jones, a running back as a freshman starter, is ticketed for flanker this fall . . .

While Washington gets the Howard Cosell game every Monday night, it seems, Warner Wolf is out there doing the alternate ABC telecasts - and taking more of the slings and arrows that have been his lot Up There on Network. Chicago Sun-Times TV critic Bill Granger was appalled, a column's worth, at the crstwhile Washington favorite's "dull" and "invariable wrong" commentary at Twins-White Sox. Only consolation was that Granger said Wolf partner Bill White was even worse . . .

Some 80 top junior (19 and under) women players have accepted invitations to tryouts for the U.S.A. Junior women's national basketball team to participate in the inaugural Pan American Confederation tournament. It will be at Squaw Valley, Calif., July 5-10, and that's where the tryouts start Thursday to pick a tem of 12. Area invitees: Betsy Bailey, Alice Bulter, Ginger Rouse . . . Swinging into action at Kuhuka, Hawaii, Monday in the AIAW National Golf Championships: Standfrod's No. 1 woman player, Sally Voss of Bethesda. Sophomore Voss was all-conference last year and this, in between coming home, where she is a Congressional C.C. regular, to win the Middle Atlantic Amateur . . .

Least we can do, with the hullaballoo over the Bullets bringing in Greg Ballard from Oregon as No. 1, is return the compliment with a bit of traffic in the other direction:

Look out, Portland State and Freeman Williams, NBA champion Trail Blazers and all, a D.C. dandy you never heard of (Neither have most folks here) is bound for your hoop-happy city: Ullysses Tucker.

A real showcase specimen for the Executive III athletic schorlarship program for capital-area marginal students directed by Harold Bates, Tucket is 6-foot-6, out of Theodore Roosevelt High. Tucker didn't get much varsity playing time in the Interhigh, but at Southeast Community College, Fairbury, Neb., which has enjoyed an Exec III pipeline for several years (back to Len Willis, et al), he was a double-figure scorer as sixth man on a 23-10 team; gave a creditable account of himself against eventual national JUCO champ Independence (Kan.). And now, he's gained a full ride to U. of Portland (rival of State and national scoring king Williams) - where he should be a success athletic and/or otherwise.

Tucker posted a formidable 3.46 grade-point average his second year at SCC-Fairbury, to go with his "street smarts," and the young man, long since parted from his parents and spending summer with his grandfather in Seat Pleasant, aims at a future in journalism - or art - or social work. He'll make it.

Executive III not only places prospects like Tucker in junior college but is prominent in the summer Urban Coalition League that offers some of the classiest basketball this side of the pros (many of whom play in it) each D.C. summer. The new season is in the offing, and Chuck Taylor, who will coach one of the teams, advises that the league this year moves from Roosevelt to the house that Elgin Baylor built" - Spingarn High gym. Taylor, who last year coached the Bullets' summer entry, this year Adrian Dantley, Mo Howard, Steve Sheppard, Ed Jordan, Charlie Floyd, Victor Kelly - plus Randolph (Apple) Milam, the "False Hopes and Broken Dreams" Post series subject detoured from pointguard greatness by a stretch in Lorton . . . Leaving player-coaching of this year's UCL Bullet team of Cap Centre rookies and young holdovers to a practiced Bullet critic, Our Own old Washington Husky, David DuPree . . .

Oh, Charlie Floyd. The sometime Wake Forest, sometime St. Joseph's student from Philly this fall takes it to Coppin State in Baltimore - same town as you'll find DuVal's All-Met forward Garcia Hopkins, newly pledged to Morgan State . . .
