Somebody observing that Walt Frazier hasn't played since Nov. 4, remarked to Coach Bill Fitch that it appeared Clyde's NBA days as a Cleveland Cavalier must be over, to which Fitch replied: "That's obvious, isn't it?"

Onetime N.Y. Knick nonpareil Frazier, 33, a $400,000-a-year player with a sore foot, angered Fitch recently by being quoted on a visit to New York: "I came to see a really good doctor. I get tired of reading where I'm taking it. (The Cav's doctors) take X-rays, and they never find anything; it's like I'm telling a lie." Frazier, who missed the last two months of last season, then was reinjured early this season, said the New York doctor found a stress fracture. Fitch said, "I resent that. Our doctors . . . are all-stars . . . the best in the league." Furthermore, Fitch said the club called the New York doctor and "he didn't say Frazier had stress fracture."

Flash!Earl Campbell is not a unanimous pic by UPI's panel of 56 writers for AFC rookie of the year. One expert went for John Jefferson, San Diego's flash from Arizona State who snare 56 passes for 1,001 yards and 13 TDs-as many as Campbell scored rushing, en route to raking in the other 55 votes . . . Wonder how injured Eddie Brown felt knowing his two replacements this year, the Rams' Jackie Wallace and Redskins' Tony Green, carried on in his tradition by finishing 1-2 among NFC punt returners? . . . And here's Brown's Washington predecessor Larry Jones, a midseason 49er cut, newly signed by the N.Y. Giants, who let him go as a rookie in 1974 despite a big pre-season.

The Phoenix Suns come in to play the Bullets Jan. 5 and it will be Curtis Perry Day in honor of the D.C. athlete whose fine NBA career was ended this year by a back ailment but remains employed by the Suns. Inner Voices, a community "social outreach" organization here, plans a 10 a.m. VIP brunch that Friday at Thursday's (above Mr. Henry's) on Pennsylvania Avenue, an award presentation at the game in Capital Centre and a disco session afterward at Harambee House to raise funds for a Curtis Perry scholarship. Perry, who attended Western High (now Ellington), has quietly done much in community good works, according to Inner Voices, particularlyin his old 12th and I Street NE neighborhood.
