Hubie Brown is about to become coach of the New York Knicks, and Dave DeBusschere to be the NBA team's general manager, according to the Associated Press.

Brown, fired as Atlanta coach March 26, 1981, has hung near pro basketball for cable TV and CBS. He won the whole ABA with the Kentucky Colonels his first try as head coach; NBA Central '80 with the Hawks. He may be introduced as soon as Wednesday as successor to venerable Red Holzman. . . .

Venerable Walter Alston and Al Lopez have been named to manage National and American League old-timers, respectively, in the Cracker Jack Baseball Classic at RFK Stadium July 19. Alston, 70, and Lopez, 73, say they'll get a kick out of pushing the buttons in the five-inning exercise in nostalgia. Promoter Dick Cecil aims for 25,000-30,000 customers . . .

Mike Weaver's turn: shoulder injury has postponed June 2 Tex Cobb bout, UPI says . . .

Jim Eisenreich, Twins' rookie center fielder with .310 B.A. and "stage fright syndrome" (hyperventilation, facial twitch): removed from five consecutive games, out the next five, now hospitalized. Trusting to psychiatric program of medication, self-hypnosis and bio-feedback, Minnesota crosses fingers . . . Break up the Yankees? Graig Nettles' broken thumb has healed--but Jerry Mumphrey's left thumb (glove hand) is fractured. Dove for a ball in Seattle, may miss six weeks. With Mumphrey to DL goes broken-knuckled Doyle Alexander--giving the Yankees one good break. Facing a month's layoff induced by punching a dugout wall after the Mariners scored five off him for Gaylord Perry, Alexander volunteers it be no play, no pay. Fine, said the brass, you're out $65,000 (est.) . . . Pete Stemkowski, ex-NHL player, admits in Mineola, N.Y., court he offered an undercover cop $20,000 to collect a $70,000 debt for him by force--"make sure to break at least one ankle and one wrist." Stemkowski, a radio-TV guy now, is out on $1,000 bail till June 22 sentencing (maximum: a year in jail) . . . In Annapolis, Alan Hangsleben, ex-Capital skater now an L.A. King but still of Upper Marlboro: charged with drunk driving, expired license, spinning wheels . . .

George Mason breaks rival recruiters' hearts: lands 6-5 all-state "muscular swing man" Dwayne (Amazing) Grace and 6-7, 198-pound Vincent McQueen, who teamed to help Bennettsville (S.C.) High win 68 of 79 games . . . Neither Maryland's Lefty Driesell nor Virginia's Terry Holland gets a break with impending word from rival Georgia Tech: it's outwooed them to win Yvon Joseph, 6-10, 235-pound talent who led Miami-Dade North to 33-1 and national JuCo runner-up status. A 3.6 student, he likes Tech's engineering curriculum. Never mind that Joseph, from Haiti, played volleyball but no basketball until August 1980, he gained all-America honorable mention for '81-82. A Miami source says he was inclined toward Virginia--as long as he thought Ralph Sampson was staying to help him break in. Hmmm.
